使用外部JS将click事件绑定到内联SVG元素

标签: jquery html css svg

我正在创建一个交互式地图,并且有点像路障。我需要发生的是基于在SVG img中单击的元素,应该出现一个工具提示窗口,其中包含有关该特定标记点的信息。

现在,我甚至无法获得任何标记来响应点击事件。以下是我正在使用的代码。一旦点击事件实际响应,我将关闭并运行。我只是坚持为什么这个点击事件没有响应(并且结果非常沮丧)。

我已阅读此SO帖子,希望了解点击回复未发生的原因:Include SVG files with HTML, and still be able to apply styles to them?以及其他几个没有适用于此方案的解决方案。正确地内联SVG,由CSS设置的悬停事件正在发生,它只是未发生的单击事件。任何帮助将不胜感激!

jQuery的:

 $(document).ready(function(){
     /*
      * Replace all SVG images with inline SVG
      */

     $('img.svg').each(function(){
     var $img = $(this);
     var imgID = $img.attr('id');
     var imgClass = $img.attr('class');
     var imgURL = $img.attr('src');

     $.get(imgURL, function(data) {
        // Get the SVG tag, ignore the rest
        var $svg = $(data).find('svg');

        // Add replaced image's ID to the new SVG
        if(typeof imgID !== 'undefined') {
            $svg = $svg.attr('id', imgID);
        }
        // Add replaced image's classes to the new SVG
        if(typeof imgClass !== 'undefined') {
            $svg = $svg.attr('class', imgClass+' replaced-svg');
        }

        // Remove any invalid XML tags as per http://validator.w3.org
        $svg = $svg.removeAttr('xmlns:a');

        // Replace image with new SVG
        $img.replaceWith($svg);

     }, 'xml');
 });
});

$(window).load(function(){
    $(".exchange-marker").bind('click', function(e){
        console.log('clicked');
        console.log($(this).attr('id'));
    });
 });

CSS:

.exchange-marker:hover{
    stroke: #fabf23;
    stroke-width: 3;
    transition: all 0.3s;
}

SVG(为简洁而截断):

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="1400" height="1200" viewBox="0 0 1400 1200">
    <g id="markers" fill="#2876BC">
        <ellipse id="exchange-1" class="exchange-marker" cx="963.8" cy="853.7" rx="14.9" ry="4.8"/>
        <ellipse id="exchange-2" class="exchange-marker" cx="929.3" cy="833.1" rx="14.9" ry="4.8"/>
    </g>
</svg>

所以解决方案归结为计算时间。通过简单地加入超时,我们就能够对应对的点击做出响应。我去参加比赛了!

jQuery的:

$(document).ready(function(){
    initSVGMap();
});

 function initSVGMap(){ 
    var $img = $('img.svg');
    var imgID = $img.attr('id');
    var imgClass = $img.attr('class');
    var imgURL = $img.attr('src');

  $.get(imgURL, function(data) {
    // Get the SVG tag, ignore the rest
    var $svg = $(data).find('svg');

    // Add replaced image's ID to the new SVG
    if(typeof imgID !== 'undefined') {
        $svg = $svg.attr('id', imgID);
    }
    // Add replaced image's classes to the new SVG
    if(typeof imgClass !== 'undefined') {
        $svg = $svg.attr('class', imgClass+' replaced-svg');
    }

    // Remove any invalid XML tags as per http://validator.w3.org
    $svg = $svg.removeAttr('xmlns:a');

    // Replace image with new SVG
    $img.replaceWith($svg);

  }, 'xml');

  setTimeout('initExchangePoints()', 1500); // THIS IS THE FIX
}

function initExchangePoints(){
    $("ellipse").each(function(){
        $(this).bind("click", function(){ console.log("Clicked " + $(this).attr("id")); });
    });
}
