heyho，

我有一个表格，我会在行动中发送给剧本。响应存储在预标记中的隐藏iframe中。我想用hquery将html-text答案存储到变量中。但问题是如何以及何时:-)！ onsubmit是提前..你能帮忙吗？

i have a form which i send to a script on action. the response is stored to a hidden iframe in pre-tags. i want to store the html-text answer to a variable with jquery. but the question is how and when :-)! onsubmit is to early.. can you help?

<form id="search" action="xyzsearchurl" target="result"> <input type="text" name="qparam" /> <input type="submit" /> </form> <iframe id="result" name="result" src="#" style="display:none;"></iframe> $('#search').submit(function(){ alert($('#result pre').html()); });

任何想法如何获得文本形式预标记后得到回复？

any ideas how to get the Text form the pre tag AFTER get the response?

非常感谢

推荐答案

您可以从iframe注册onload事件然后阅读内容。 注意：这仅在从同一服务器加载帧时才有效（同源策略）

You can register the onload event from the iframe and then read the content. Note: this will only work if the frame is loaded from the same server (same origin policy)

$('#search').submit(function(){ //register load event of iframe... $('#result').load(function() { $("#result").contents().find("what you need..."); }); });
