AJAX问题 [英] AJAX Issue
问题描述
我正在使用AJAX XMLhttprequest来请求表单上的另一个页面提交
并且我将该页面加载到span标记中。我的问题是，我在被调用的页面中有更多的js来点击文本
框来加载日历。这个日历永远不会加载到我的页面中，但是如果我在新窗口中通过
本身调用页面，javascript工作正常，任何想法？见下面
当你打电话给索引并点击按钮时页面没有显示
警报，当你直接打电话给getcall时，警报显示正常。

I am using AJAX XMLhttprequest to request another page on form submit
and I am loading that page into a span tag. My issue is that I have
more js in the called page that loads a calendar on click of a text
box. This calendar never loads in my page but if I call the page by
itself in a new window javascript works fine, any ideas? See Below
when you call index and click the button the page does not show the
alert, when you call getcall straight the alert shows fine.
index.asp
<form name="new" method="Post"
action="javascript:get(document.getElementById(''ne w''),''new'');">
<input type="Submit" name="Submit" value="Enter New Call"><br>
</form>
<span name="call_results" id="call_results"></span>
getcall.asp
<SCRIPT type="text/javascript">
alert("here");
</SCRIPT>

通过innerHMTL插入脚本代码不会执行它（只有在NS6中才能执行
）。如果你想执行脚本代码，你将不得不单独加载它，使用createElement创建一个脚本块，然后
appendChild将该脚本块附加到任何现代浏览器都可以在
中执行一个节点。

Inserting script code via innerHMTL won''t execute it (only in NS6 did
that work). If you want to execute script code, you are going to have to
load it separately, use createElement to create a script block, then
appendChild to append that script block to a node for it to execute in
any modern browser.

Randy，我有没有办法用我正在传递的innerHTML来做这件事/>
而不是使用create元素？我在
调用页面中创建了一个日历对象，这根本不表现....我试图这样做
但它没有工作......
当我填充我使用的跨度....
result = http_request.responseText;
result = execJS（result）;
document.getElementById（''call_results''）。innerHTML = result;
exec function ...
函数execJS（节点）{
var st = node.getElementsByTagName（''SCRIPT''）;
var strExec;
for（var i = 0; i< st.length; i ++）{
strExec = st [i] .text;
try {
eval（strExec）;
} catch（e）{
alert（e）;
}
}
}
它在getElementsByTagName上打嗝我知道为什么但是当我发出警报时我还能用什么来使用
节点字符串它具有我正在使用的所有页面
填充页面，但我无法让最后一块工作，我有
一直在读这个我在这种情况下可以使用eval函数 -
http://microformats.org/wiki/rest/ah...ing_Javascript
有什么想法吗？
在我写完上面之后我有了一个重大突破....
result = http_request.responseText;
document.getElementById（''call_results''）。innerHTML = result;
var d = call_results.getElementsByTagName（" script"）;
for（var x = 0; x< d.length; x ++）{
with（window）{
eval（d [x] .text）;
}
}
像魅力一样工作。
right after I wrote the above I had a major breakthrough....
result = http_request.responseText;
document.getElementById(''call_results'').innerHTML = result;
var d=call_results.getElementsByTagName("script");
for(var x=0;x<d.length;x++) {
with(window) {
eval(d[x].text);
}
}
Works like a charm.
