问题描述

我正在创建一个输入范围滑块，允许用户选择1992-2017年范围内的年份. 我正在使用最佳jQuery库.

这是我创建的: PLUNKER . /p>

html :

<div id='slider2'>
    <div id="circles-slider"></div>
</div>

css :

body {
    font-size: 9pt;
    font-family: 'Roboto', sans-serif;
    font-weight: 300;
}

#slider2 {
    padding: 30px;
    width: 500px;
    background-color: lime;
}

#circles-slider.ui-slider {
    border-radius: 20px;
    background: #434d5a;
    border: none;
    height: 10px;
    margin: 1em 4em 4em; 
}

#circles-slider .ui-slider-handle {
    border-radius: 18px;
    height: 18px;
    width: 18px;
    top: -4px;
    margin-left: -9px;
    border: 1px solid white; 
}

#circles-slider .ui-slider-pip {
    top: 3px; 
}

#circles-slider .ui-slider-pip .ui-slider-line {
    width: 4px;
    height: 4px;
    border-radius: 4px;
    margin-left: -2px;
    background: white; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last,
#circles-slider .ui-slider-pip.ui-slider-pip-first {
    top: -7px; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-line,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-line {
    display: none; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    margin: 0; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    left: -2em;
    text-align: right; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label {
    left: 2em;
    text-align: left; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
    font-weight: normal; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected {
    font-weight: bold; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected,
#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
    color: #434d5a; 
}

.ui-slider-pips .ui-slider-label {
    color: black;
    top: 7px;
}

.ui-slider-label {
    margin-top: 6px;
}

js :

var labels = [];
labels[0] = "1992";
labels[5] = "1997";
labels[10] = "2002";
labels[15] = "2007";
labels[20] = "2012";
labels[25] = "2017";

$("#circles-slider")
.slider({
    min: 1992, 
    max: 2017, 
    value: 2016,
    step: 1
})
.slider("pips", {
    first: "label",
    last: "label",
    rest: "label",
    labels: labels,
    step: 1
})
.slider("float", {
    labels: labels
});

这就是我想要得到的:

我快到了.但是，我想要这样:

  1. 所有标签都位于灰线的底部(即使是1992年初和2017年底标签)
  2. 与年份相关的点的颜色与其他颜色不同(在本例中为橙色)
  3. 所选年份位于滑块的右侧
  4. 绿色空间太大，我无法处理.它应该小得多(必须包含所选年份的滑块和标签).

我需要帮助.

解决方案

演示: https://plnkr.co/edit/fT0Kbgwl9oEKSpf8dmwI?p=preview

  1. 您已经添加了一些额外的样式，需要删除这些样式才能将第一个标签和最后一个标签置于滑块下方.

 #circles-slider .ui-slider-pip.ui-slider-pip-last,
#circles-slider .ui-slider-pip.ui-slider-pip-first {
    top: -7px; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-line,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-line {
    display: none; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    margin: 0; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    left: -2em;
    text-align: right; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label {
    left: 2em;
    text-align: left; 
}

  1. 您需要根据我的理解为每第5个点上色.您可以使用:

 #circles-slider .ui-slider-pip:nth-child(5n+2) .ui-slider-line{
   background-color: orange;
}

PS:5n应该可以工作了.我需要再次检查.

  1. 我已经通过使用slide2上的flex布局并将.ui-slider的宽度设置为85％来做到这一点.因此，您的HTML应该像这样:

 <div id='slider2'>
  <div id="circles-slider">
  </div>
  <span id="selected-year-label"></span>
</div>

  1. 您可以根据需要通过#slider2和.ui-slider的边距和填充进行操作.

要更新滑块上的当前值，我添加了slidechange事件侦听器.因此，您的JS变为:

 const SLIDER_INITIAL_VAL = 2016;
var labels = [];
labels[0] = "1992";
labels[5] = "1997";
labels[10] = "2002";
labels[15] = "2007";
labels[20] = "2012";
labels[25] = "2017";

$("#circles-slider")
  .slider({
    min: 1992,
    max: 2017,
    value: SLIDER_INITIAL_VAL,
    step: 1
  })
  .slider("pips", {
    first: "label",
    last: "label",
    rest: "label",
    labels: labels,
    step: 1
  });

$("#selected-year-label").html(SLIDER_INITIAL_VAL);

$("#circles-slider").on("slide.selectPip slidechange.selectPip", function(e, ui) {
  var slider_val = $("#circles-slider .ui-slider-pip-selected .ui-slider-label").attr("data-value");
  $("#selected-year-label").html(slider_val);
});

下面的CSS可以编译以上所有内容，并且应该对您有用:

 body {
  font-size: 9pt;
  font-family: 'Roboto', sans-serif;
  font-weight: 300;
}

#slider2 {
  padding: 10px;
  width: 500px;
  background-color: lime;
  display: flex;
}

#circles-slider.ui-slider {
  margin: 1em 1em 2em;
  width: 85%;
}

#circles-slider.ui-slider::before {
  content: "";
  position: absolute;
  right: -4%;
  left: -4%;
  background: #434d5a;
  height: 10px;
  border: none;
  border-radius: 20px;
}

#selected-year-label {
  margin-top: 10px;
  margin-left: 10px;
}

#circles-slider .ui-slider-handle {
  border-radius: 18px;
  height: 18px;
  width: 18px;
  top: -4px;
  margin-left: -9px;
  border: 1px solid white;
}

#circles-slider .ui-slider-pip {
  top: 3px;
}

#circles-slider .ui-slider-pip:nth-child(5n+2) .ui-slider-line {
  background-color: orange;
}

#circles-slider .ui-slider-pip .ui-slider-line {
  width: 4px;
  height: 4px;
  border-radius: 4px;
  margin-left: -2px;
  background: white;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
  font-weight: normal;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected {
  font-weight: bold;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected,
#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
  color: #434d5a;
}

.ui-slider-pips .ui-slider-label {
  color: black;
  top: 7px;
}

.ui-slider-label {
  margin-top: 6px;
}

I am creating an input range slider that allows the user to choose a year in the 1992-2017 range. I'm using the Best jQuery library.

Here's what I created: PLUNKER.

html:

<div id='slider2'>
    <div id="circles-slider"></div>
</div>

css:

body {
    font-size: 9pt;
    font-family: 'Roboto', sans-serif;
    font-weight: 300;
}

#slider2 {
    padding: 30px;
    width: 500px;
    background-color: lime;
}

#circles-slider.ui-slider {
    border-radius: 20px;
    background: #434d5a;
    border: none;
    height: 10px;
    margin: 1em 4em 4em; 
}

#circles-slider .ui-slider-handle {
    border-radius: 18px;
    height: 18px;
    width: 18px;
    top: -4px;
    margin-left: -9px;
    border: 1px solid white; 
}

#circles-slider .ui-slider-pip {
    top: 3px; 
}

#circles-slider .ui-slider-pip .ui-slider-line {
    width: 4px;
    height: 4px;
    border-radius: 4px;
    margin-left: -2px;
    background: white; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last,
#circles-slider .ui-slider-pip.ui-slider-pip-first {
    top: -7px; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-line,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-line {
    display: none; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    margin: 0; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    left: -2em;
    text-align: right; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label {
    left: 2em;
    text-align: left; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
    font-weight: normal; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected {
    font-weight: bold; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected,
#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
    color: #434d5a; 
}

.ui-slider-pips .ui-slider-label {
    color: black;
    top: 7px;
}

.ui-slider-label {
    margin-top: 6px;
}

js:

var labels = [];
labels[0] = "1992";
labels[5] = "1997";
labels[10] = "2002";
labels[15] = "2007";
labels[20] = "2012";
labels[25] = "2017";

$("#circles-slider")
.slider({
    min: 1992, 
    max: 2017, 
    value: 2016,
    step: 1
})
.slider("pips", {
    first: "label",
    last: "label",
    rest: "label",
    labels: labels,
    step: 1
})
.slider("float", {
    labels: labels
});

This is what I would like to get:

I'm almost there. I would however like that:

  1. all the labels are bottom the grey line (even the start 1992 and end 2017 labels)
  2. the dots relating to the years with the label have a different color than the others (in this case they are orange)
  3. the selected year is positioned to the right of the slider
  4. the green space is too large, I can not handle it. It should be much smaller (necessary to contain the slider and the label of the chosen year).

I need help.

  1. You've added some extra styles which you need to remove to get the first and last labels below the slider.

#circles-slider .ui-slider-pip.ui-slider-pip-last,
#circles-slider .ui-slider-pip.ui-slider-pip-first {
    top: -7px; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-line,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-line {
    display: none; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label,
#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    margin: 0; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-first .ui-slider-label {
    left: -2em;
    text-align: right; 
}

#circles-slider .ui-slider-pip.ui-slider-pip-last .ui-slider-label {
    left: 2em;
    text-align: left; 
}

  1. You need to color every 5th dot from what i understand. You can do this using:

#circles-slider .ui-slider-pip:nth-child(5n+2) .ui-slider-line{
   background-color: orange;
}

PS: 5n should have worked. I need to check this again.

  1. I've done this by using the flex layout on slider2 and setting the width of .ui-slider 85%. So your HTML should be like:

<div id='slider2'>
  <div id="circles-slider">
  </div>
  <span id="selected-year-label"></span>
</div>

  1. You can do this by playing with the margin and padding of #slider2 and .ui-slider as per your needs.

To update the current value on slider I've added the slidechange event listeners. So your JS becomes:

const SLIDER_INITIAL_VAL = 2016;
var labels = [];
labels[0] = "1992";
labels[5] = "1997";
labels[10] = "2002";
labels[15] = "2007";
labels[20] = "2012";
labels[25] = "2017";

$("#circles-slider")
  .slider({
    min: 1992,
    max: 2017,
    value: SLIDER_INITIAL_VAL,
    step: 1
  })
  .slider("pips", {
    first: "label",
    last: "label",
    rest: "label",
    labels: labels,
    step: 1
  });

$("#selected-year-label").html(SLIDER_INITIAL_VAL);

$("#circles-slider").on("slide.selectPip slidechange.selectPip", function(e, ui) {
  var slider_val = $("#circles-slider .ui-slider-pip-selected .ui-slider-label").attr("data-value");
  $("#selected-year-label").html(slider_val);
});

Below CSS compiles all the above and should work for you:

body {
  font-size: 9pt;
  font-family: 'Roboto', sans-serif;
  font-weight: 300;
}

#slider2 {
  padding: 10px;
  width: 500px;
  background-color: lime;
  display: flex;
}

#circles-slider.ui-slider {
  margin: 1em 1em 2em;
  width: 85%;
}

#circles-slider.ui-slider::before {
  content: "";
  position: absolute;
  right: -4%;
  left: -4%;
  background: #434d5a;
  height: 10px;
  border: none;
  border-radius: 20px;
}

#selected-year-label {
  margin-top: 10px;
  margin-left: 10px;
}

#circles-slider .ui-slider-handle {
  border-radius: 18px;
  height: 18px;
  width: 18px;
  top: -4px;
  margin-left: -9px;
  border: 1px solid white;
}

#circles-slider .ui-slider-pip {
  top: 3px;
}

#circles-slider .ui-slider-pip:nth-child(5n+2) .ui-slider-line {
  background-color: orange;
}

#circles-slider .ui-slider-pip .ui-slider-line {
  width: 4px;
  height: 4px;
  border-radius: 4px;
  margin-left: -2px;
  background: white;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
  font-weight: normal;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected {
  font-weight: bold;
}

#circles-slider .ui-slider-pip.ui-slider-pip-selected,
#circles-slider .ui-slider-pip.ui-slider-pip-selected-initial {
  color: #434d5a;
}

.ui-slider-pips .ui-slider-label {
  color: black;
  top: 7px;
}

.ui-slider-label {
  margin-top: 6px;
}
