问题描述

在单击时,我使用纯javascript将一个类分配给元素(SVG PATH):

On a click I assign a class to my element (SVG PATH) using pure javascript:

this.getElement().classList.add('active');

新类是它已经拥有的其他一系列类的一部分.但是,一旦将这个新类添加到clicked元素中,它还应该为html中具有与clicked元素本身具有任何匹配类的其他元素提供一个.active类.

The new class is part of a series of other classes it already has. However once this new class is added to the clicked element, it should also give a class .active to other elements in the html which have any matching classes with the clicked element itself.

html:

<button class="1600 1500"></button>
<button class="1600 1300 1200"></button>
<button class="1300 1200 1700 1800"></button>    
<button class="1300 1200 1100 1900"></button>

<div class="1600 1700 item leaflet"></div>

我不知道哪个按钮具有匹配的类,因为这些类也是动态的.我所知道的是,div将具有与任何按钮的类匹配的任何类.

I don't know which button has a matching class since those classes are dynamic too. All I know is that the div will have any class matching any button's class.

问题在于,出于特定原因,我在点击div时使用纯JavaScript来分配新的类名称(作品):

The thing is that for specific reasons I am using pure javascript to assign a new class name on click on the div (works):

this.getElement().classList.add('active');

因此以下操作将无效:

this.click(function() {
  var classes = this.attr('class').split(' ')
  classes.forEach(function(elem) {
    $('.' + elem).addClass('active');
  });
});

这就是我所说的点击":

This how i call the click:

function onEachFeature(feature, layer) {
    layer.on({
        click: panelShow
    });
}

function panelShow(e) {
    // This works, the class is added to the clicked element
    this.getElement().classList.add('active');
}

但是我在此之外还有其他按钮,需要根据问题激活一个班级.

But I have buttons outside this and needs to have a class active as per the question.

在div点击后需要

Desired after the div click

<div class="1600 1700 item leaflet active"></div>

<button class="1600 1500 active"></button>
<button class="1600 1300 1200 active"></button>
<button class="1300 1200 1700 1800 active"></button>
<button class="1300 1200 1100 1900"></button>

这就是我如何处理相反的情况,单击按钮(然后 作品):

This is how I deal with the opposite, clicking on the buttons (and works):

var date;
$("button").on("click", function(b) {

    date = $(this).attr("data-date");

    $('path').attr('class', function(index, classNames) {
        return classNames.replace('active', '');
    });

   $("svg ." + date).attr('class', function(index, classNames) {
        return classNames + ' active';
    });

    $(".btn").removeClass("active");
    $(this).addClass("active");
 });

注意

在现实生活中,我正在使用data attribute按钮,但将其视为 此处的示例问题的类,只是我所编写的更复杂代码中的粘贴.

In real life on the buttons I am using data attribute but consider it as a class for the example question on here, it's just a paste from a more complex code I have.

我也在使用 leafletsJS ,这就是javascript单击的原因 上面的功能.

Also I am using leafletsJS, that's why the javascript click in the function above.

推荐答案

一个选项是:

var buttons = [].slice.call(document.querySelectorAll('.buttons button'));

function panelShow(e) {
  $("path").removeClass("active");
  var clickedPath = this.getElement();
  clickedPath.classList.add("active");
  var datum = (clickedPath.getAttribute('class').match(/\d+/g) || [])[0];
  buttons.forEach(function(btn) {
    var method = btn.getAttribute('data-date') === datum ? 'add' : 'remove';
    btn.classList[method]('active');
  });
}
