Question

是否有可能有一个按钮，当点击它将提取特定div标签内的整个代码？在javescript，jquery还是php中有可能吗？

比如说：

<div class="extactMe">
<a href="http://stackoverflow.com"><img src="icon.png"></a>
</div>

如果我点击按钮＆＃34;提取＆＃34;例如，在网页上，<div class="extactMe">到</div>的整个div标签将被复制到textarea。请指教，谢谢。

您可以使用URLToReplace = http://www.xf.com/position/?number=1&From=X&To=Y URLToCrawl = replaceElementXY(URLToReplace, "left", "right") print URLToCrawl // Display: http://www.xf.com/position/?number=1&From=left&To=right属性来实现此目的。试试这个：

你试过吗？

var extracted = $('.extractMe').html();

Answer 3

JSFiddle的完整示例：https://jsfiddle.net/jo37u3xs/

这里不涉及PHP。

Javascript部分：

$(document).ready(function() {

    // when you click the button
    $("#button-extract").click( function() {

        // get the html of the div
        var divContent = $('div.extractMe').html();

        // insert the html of the div into the textarea
        $("textarea#my-textarea").val(divContent);        
    });
});

HTML：

<div class="extractMe">
   <a href="http://stackoverflow.com"><img src="icon.png">Yo, man. The image is missing.</a><br/>
</div>

<br/>    

<button type="button" id="button-extract">Extract</button>

<br/><br/>   

 <textarea cols="50" rows="10" id="my-textarea">
Its empty at the start. Err, not really.
</textarea>

请查看以下jQuery函数以了解它们的作用：

。点击（）
html的（）
.val（）
和jQuery选择器：$（“。class”）和$（“＃id”）
