从< a>获取href值标签 [英] getting href value of from <a> tag
本文介绍了从< a>获取href值标签的处理方法，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
我有下面的html：
< div class =threeimagesid =txtCss>
< a>
< / a>
< div class =textid =txtLink>
< h2>
< a href =/ partnerzone / downloadarea / school-information / australia / index.aspx>澳大利亚< / a>
< / h2>
< p>阳光之地！< / p>
< / div>
< / div>
现在，如果您看到div ID为txtLink中有href，即
回到2009年，尽管使用jquery是完全可以接受的：）
用这样的东西创建一个js文件：
$（document）.ready（function（）{
$（'。threeimages'）。each（function（）{
$（this）.DupeHref（）;
}）;
}）;
jQuery.fn.DupeHref = function（）{
var target = $（this）.find（。text h2 a）。attr（href）;
$（this）.find（a）。attr（href，target）;
}
在html中引用jquery和这个javascript文件。
类似于这样：
<！DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Strict / / ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">
< html xmlns =http://www.w3.org/1999/xhtml>
< head>
< meta http-equiv =Content-Typecontent =text / html; charset = utf-8/>
< title>测试< /标题>
< / head>
< body>
< div class =threeimages>
< a>
< / a>
< div class =text>
< h2>
< a href =/ partnerzone / downloadarea / school-information / australia / index.aspx>澳大利亚< / a>
< / h2>
< p>阳光之地！< / p>
< / div>
< / div>
< div class =threeimages>
< a>
< img alt =比利时src =/ Images / Services％20button_tcm7-9689.gif/>
< / a>
< div class =text>
< h2>
< a href =/ partnerzone / downloadarea / school-information / belgium / index.aspx>比利时< / a>
< / h2>
< p>啤酒和食物之地！< / p>
< / div>
< / div>
< script src =./ content / js / jquery-1.2.6.min.jstype =text / javascript>< / script>
< script src =./ content / js / dupetargets.jstype =text / javascript>< / script>
< / body>
< / html>
I have below html:
<div class="threeimages" id="txtCss">
<a>
<img alt="Australia" src="/Images/Services%20button_tcm7-9688.gif"/>
</a>
<div class="text" id="txtLink">
<h2>
<a href="/partnerzone/downloadarea/school-information/australia/index.aspx">Australia</a>
</h2>
<p>Land of the sunshine!</p>
</div>
</div>
Now if you see there is href in div ID "txtLink" i.e. Australia
I want this at the runtime of page the same href values get copied into above tag of div ID "txtCss", I mean when my page gets displayed my html will be as below:
<div class="threeimages" id="txtCss">
<a href="/partnerzone/downloadarea/school-information/australia/index.aspx">
<img alt="Australia" src="/Images/Services%20button_tcm7-9688.gif"/>
</a>
<div class="text" id="txtLink">
<h2>
<a href="/partnerzone/downloadarea/school-information/australia/index.aspx">Australia</a>
</h2>
<p>Land of the sunshine!</p>
</div>
</div>
please suggest some code for above problem
解决方案
Update
An answer without jquery here: https://stackoverflow.com/a/887348/11333
Back in 2009 it was perfectly acceptable to use jquery though :)
Create a js file with something like this:
$(document).ready(function() {
$('.threeimages').each(function(){
$(this).DupeHref();
});
});
jQuery.fn.DupeHref = function(){
var target = $(this).find(".text h2 a").attr("href");
$(this).find("a").attr("href", target);
}
Reference both the jquery and this javascript file in your html. Something like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
</head>
<body>
<div class="threeimages">
<a>
<img alt="Australia" src="/Images/Services%20button_tcm7-9688.gif"/>
</a>
<div class="text">
<h2>
<a href="/partnerzone/downloadarea/school-information/australia/index.aspx">Australia</a>
</h2>
<p>Land of the sunshine!</p>
</div>
</div>
<div class="threeimages">
<a>
<img alt="Belgium" src="/Images/Services%20button_tcm7-9689.gif"/>
</a>
<div class="text">
<h2>
<a href="/partnerzone/downloadarea/school-information/belgium/index.aspx">Belgium</a>
</h2>
<p>Land of beer and food!</p>
</div>
</div>
<script src="./content/js/jquery-1.2.6.min.js" type="text/javascript"></script>
<script src="./content/js/dupetargets.js" type="text/javascript"></script>
</body>
</html>
