为父属性中的多个元素添加一个前缀
为父属性中的多个元素添加一个前缀
提问于 2018-02-24 21:42:41
我试图弄清楚如何在ID和其他引用链接中添加一个唯一的前缀。
一个页面上有多个相同的SVG。这些SVG充当包装器(它们是设备--笔记本电脑、电话等)其中有图像链接，加载后插入到SVG中。问题是，这些svg的ID是相同的，所以它们都相互冲突。我想要做的(但对更好的解决方案开放)是为每个id、xlink:href、url(#等插入一个唯一的ID，但是传递<image> href属性以及fill和stroke属性。
编辑：我添加/调整了@Temani提供的代码，这使我更接近我想要的结果，但是，我现在正在将所有ID添加到每个SVG元素中。格式化要可执行的代码。
期望输出：
<div class="device" data-screen="[[IMAGE TO USE]]" data-name"[[UNIQUE ID]]">
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="635" height="420" viewBox="0 0 635 420">
<defs>
<path id="[[UNIQUE ID]]-path-1"/>
<rect id="[[UNIQUE ID]]-path-3" />
<pattern id="[[UNIQUE ID]]-pattern-4">
<use transform="scale(13.1875)" xlink:href="#[[UNIQUE ID]]-image-5"/>
</pattern>
<image id="[[UNIQUE ID]]-image-5" href="[[IMAGE LINK THAT IS INSERTED AFTER LOAD]]"/>
</defs>
<g fill="none" fill-rule="evenodd">
<rect fill="#fff" stroke="#2D8EFF" />
<g >
<mask id="[[UNIQUE ID]]-mask-2" fill="#fff">
<use xlink:href="#[[UNIQUE ID]]-path-1"/>
</mask>
<g mask="url(#[[UNIQUE ID]]-mask-2)">
<mask id="mask-6" fill="#fff">
<use xlink:href="#[[UNIQUE ID]]-path-3"/>
</mask>
</g>
</g>
</g>
</svg>
</div>现在-两个ID(第一个和第二个)被添加到每个SVG元素中。我也
$('.device').each(function() {
//we get the needed id using $(this) that refer to actual device
var id = $(this).data('name');
//we check all the element with ID
$(this).find("path, rect, pattern, image, mask").each(function() {
//now (this) refer to the actual element
if($(this).attr("id"))
$(this).attr("id", id+"-"+$(this).attr("id"));
});
//we update the <use>
$(this).find("use").each(function() {
//now (this) refer to the actual element
$(this).attr("xlink:href","#"+id+"-"+$(this).attr("xlink:href").substring(1));
});
// Also, hoping to combine g[mask], u[fill], etc into 1 function.
// Basically any attribute that starts with "url(#"
$(this).find("g[mask^='url']").each(function() {
$(this).attr("mask","url(#"+id+"-"+$(this).attr("mask").substring(5));
});
$(this).find("use[fill^='url']").each(function() {
$(this).attr("fill","url(#"+id+"-"+$(this).attr("fill").substring(5));
});
$(this).find("use[filter^='url']").each(function() {
$(this).attr("filter","url(#"+id+"-"+$(this).attr("filter").substring(5));
});
// grab data-screen value
var data = $(this).data('screen');
// replace this with the link inside svg
if (data != '') {
$(this).find("svg defs image").attr("href", data).attr("xlink:href", data);
}

问题是，您不需要在内部使用$('.device')，您需要引用$(this)，并且由于您有2个each()嵌套，所以需要注意this的范围。
$('.device').each(function() {
//we get the needed id using $(this) that refer to actual device
var id = $(this).data('name');
//we check all the element with ID
$(this).find("path, rect, pattern, image, mask").each(function() {
//now (this) refer to the actual element
if($(this).attr("id"))
$(this).attr("id", id+"-"+$(this).attr("id"));
});
//we update the <use>
$(this).find("use").each(function() {
//now (this) refer to the actual element
$(this).attr("xlink:href","#"+id+"-"+$(this).attr("xlink:href").substring(1));
});
// grab data-screen value
var data = $(this).data('screen');
// replace this with the link inside svg
if (data != '') {
$(this).find("svg defs image").attr("href", data).attr("xlink:href", data);
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="device" data-screen="[[IMAGE TO USE]]" data-name="[[UNIQUE ID]]">
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="635" height="420" viewBox="0 0 635 420">

<path id="path-1"/>
<rect id="path-3" />
<pattern id="pattern-4">
<use transform="scale(13.1875)" xlink:href="#image-5"/>
</pattern>
<image id="image-5" href="[[IMAGE LINK THAT IS INSERTED AFTER LOAD]]"/>
</defs>
<g fill="none" fill-rule="evenodd">
<rect fill="#fff" stroke="#2D8EFF" />
<g >
<mask id="mask-2" fill="#fff">
<use xlink:href="#path-1"/>
