本文介绍了从一个div转移溢出到另一个的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

情况:我有两个固定高度的div,溢出设置为隐藏在两者上,和第一个div中的动态文本内容。如果该内容超过第一个div的溢出边界,我想要它自动溢出到第二个div。



我的问题是怎么做的?我研究了,我发现的最接近的事情是一个JQuery插件,自动创建一个报纸类布局的列。虽然这不完全是我需要的,但它确实让我希望这是可以在更简单的水平上实现。



视觉效果:

 < html> 
< head>
< style type =text / css>
div {height:1in; width:4in; overflow:hidden}
< / style>
< / head>
< body>
< div id =d1> ...(足以导致溢出超过1in高度的文字)...< / div>
< div id =d2> ...(从第一个div中截取的文本的其余部分)...< / div>
< / body>
< / html>

感谢大家!基于所有的输入,我把这一起。注意:这可能不适合每个人的目的:


  1. 我在JQuery中使用了


  2. 每个额外的项目都有自己的元素,而不只是打开的文本

  3. 我已经知道为了我的需要一个div不会破坏溢出限制

这就是说:



HTML

 < html> 
< head>
< style type =text / css>
#base {border:1px black solid; height:2in; width:3in; overflow:hidden;}
#overflow {border:1px black solid; width:3in;}
.content {width:2in}
< / style>
< script type =text / javascriptsrc =ref / js / jquery-1.6.2.min.js>< / script>
< script type =text / javascriptsrc =work.js>< / script>
< / head>
< body>
< div id =base>
< div id =sub>< / div>
< / div>
< br />
< div id =overflow>
< / div>




  $(document).ready(function(){

//但是你希望
var items = new Array();
items [0] ='< div class =contentid =C0style =border:1px blue solid; height:。 75in> content 1< / div>';
items [1] ='< div class =contentid =C1style =border:1px green solid; height:.75in> ; content 2< / div>';
items [2] ='< div class =contentid =C2style =border:1px red solid; height:.75in> content 3< ; / div>';
items [3] ='< div class =contentid =C3style =border:1px yellow solid; height:.75in> content 4< / div ;';
items [4] ='< div class =contentid =C4style =border:1px orange solid; height:.75in> content 5< / div>

//具有固定宽度的父div的高度变量
var baseheight = $(#base)css('height')。substring(0,$ #base)css('height')。length-2);

//在固定宽度div内动态获取子div的高度的函数
function subheight ){return $(#sub)。css('height')。substring(0,$(#sub)。css('height')。length-2);}
$ b b //对于每个单独的内容...
for(i = 0; i {
//将其添加到子div中
$(#sub)。append(items [i]);

//父和子div之间的高度差异的变量
var diff = subheight() - baseheight;

//如果这段内容导致溢出...
if(diff> 0)
{

//删除...
var tooMuch =#C+ i; $(tooMuch).remove();

//将它放在overflow div中,而不是
$(#overflow)。append(items [i]);
}
}

});


解决方案



您在JS中应该做什么:


  1. 获得< c $ c> cont1

  2. 当内容加载到 cont1 >< p> 高

  3. 如果< p> c> c1> c> c1> 的高度,从< p> ,直到它的高度等于或小于 cont1

  4. 删除的文本第二个 cont2 。将< p> 中的文本换行,以便如果您计划再次执行此专长,则有2个容器可以再次处理。

不是最优雅的代码(当内容非常长时,循环会延迟),但值得一试



HTML:

 code>< div id =cont1> 
< p>长文字在这里< / p>
< / div>
< div id =cont2>
< p><! - 未来内容 - >< / p>
< / div>

CSS:

 code>#cont1 {
height:100px;
background:red;
margin-bottom:10px;
padding:10px;
}
#cont2 {
height:100px;
background:blue;
margin-bottom:10px;
padding:10px;
}



JS:

  //现有文本必须在第一个容器中渲染,所以我们知道它与div 

//获取引用以避免jQuery中的开销
var cont1 = $('#cont1');
var cont1Height = cont1.height();

var p1 = $('#cont1 p');
var p1Height = p1.height();

var p2 = $('#cont2 p');

//获取文本并将其作为数组展开
var p1text = p1.text();
p1text = p1text.split('');

//准备p2文本
p2text = [];

//如果更大的高度
while(p1Height> cont1Height){

//删除最后一个字符
lastChar = p1text.pop

//添加到p2文本
p2text.unshift(lastChar);

//重新组合p1文本
p1temp = p1text.join('');

//放回p1
p1.text(p1temp);

//重新评估高度
p1Height = p1.height();

// loop
}

//如果小于,汇编p2文本并渲染到p2容器
p2.text(p2text.join ''));


Situation: I have two fixed-height divs, overflow set to hidden on both, and dynamic text content within the first div. Should that content exceed the overflow boundaries of the first div, I would like for it to automatically spill into the second div.

My questions is simply how to do this? I've researched, and the closest thing I found was a JQuery plugin that automatically creates columns for a newspaper-like layout. While this is not exactly what I need, it does give me hope that this is achievable on a simpler level.

Visual Example:

  <html>
     <head>
       <style type="text/css">
          div{height:1in;width:4in;overflow:hidden}
        </style>
     </head>
    <body>
     <div id="d1">...(enough text to cause overflow exceeding 1in height)...</div>
     <div id="d2">...(the rest of the text that got cut off from the first div)...</div>
    </body>
   </html>

Thanks everyone! Based on all the input, I put this together. NOTE: this may not suit everyone's purpose:

  1. I did it in JQuery
  2. This is very conceptual
  3. Each additional item it its own element, and not just open text
  4. I already know for my needs that a single div will not break the overflow limits

That being said:

HTML

<html>
<head>
<style type="text/css">
    #base{border:1px black solid;height:2in;width:3in;overflow:hidden;}
    #overflow{border:1px black solid;width:3in;}
    .content{width:2in}
</style>
<script type="text/javascript" src="ref/js/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="work.js"></script>
</head>
<body>
<div id="base">
    <div id="sub"></div>
</div>
<br />
<div id="overflow">
</div>

JQ

$(document).ready(function(){

//  An array of content, loaded however you wish
var items=new Array();
items[0]='<div class="content" id="C0" style="border:1px blue solid;height:.75in">content 1</div>';
items[1]='<div class="content" id="C1" style="border:1px green solid;height:.75in">content 2</div>';
items[2]='<div class="content" id="C2" style="border:1px red solid;height:.75in">content 3</div>';
items[3]='<div class="content" id="C3" style="border:1px yellow solid;height:.75in">content 4</div>';
items[4]='<div class="content" id="C4" style="border:1px orange solid;height:.75in">content 5</div>';

//  Variable for the height of the parent div with the fixed width
var baseheight=$("#base").css('height').substring(0,$("#base").css('height').length-2);

//  Function to dynamically get the height of the child div within the fixed width div
function subheight(){return $("#sub").css('height').substring(0,$("#sub").css('height').length-2);}

// For each individual piece of content...
for(i=0;i<items.length;i++)
    {
    //  Add it to the child div
    $("#sub").append(items[i]);

    // Variable for the difference in height between the parent and child divs
    var diff=subheight()-baseheight;

    //  If this piece of content causes overflow...
    if(diff>0)
        {

        // Remove it...
        var tooMuch="#C"+i;$(tooMuch).remove();

        // And put it in the overflow div instead
        $("#overflow").append(items[i]);
        }
    }

});

解决方案

this is sort of JS only.

what you should do in JS:

  1. get the height of cont1
  2. when content is loaded to cont1, get the <p> height
  3. if <p>'s height > cont1's height, remove text (and store it to a temporary variable) starting from the end of of the text in<p>'s until it's height is equal or lesser than cont1.
  4. the removed text (which was stored earlier) will be dumped into the second cont2. wrap the text in <p> so that if you plan to do this feat again, you have 2 containers to deal with again.

not the most elegant of code (loop will lag when content is very long), but it's worth a try

HTML:

<div id="cont1">
    <p>long text here</p>
</div>
<div id="cont2">
    <p><!-- future content --></p>
</div>

CSS:

#cont1{
    height:100px;
    background:red;
    margin-bottom:10px;
    padding:10px;
}
#cont2{
    height:100px;
    background:blue;
    margin-bottom:10px;
    padding:10px;
}

JS:

//existing text must be rendered in the first container so we know how high it is compared to the div

//get references to avoid overhead in jQuery
var cont1 = $('#cont1');
var cont1Height = cont1.height();

var p1 = $('#cont1 p');
var p1Height = p1.height();

var p2 = $('#cont2 p');

//get text and explode it as an array
var p1text = p1.text();
p1text = p1text.split('');

//prepare p2 text
p2text = [];

//if greater height
while (p1Height > cont1Height) {

    //remove last character
    lastChar = p1text.pop();

    //prepend to p2 text
    p2text.unshift(lastChar);

    //reassemble p1 text
    p1temp = p1text.join('');

    //place back to p1
    p1.text(p1temp);

    //re-evaluate height
    p1Height = p1.height();

    //loop
}

//if less than, assemble p2 text and render to p2 container
p2.text(p2text.join(''));​
