我有，当你提交，它发送的数据进行验证，以另一种PHP脚本通过AJAX的形式。验证错误echo'd回来在我的形式股利。成功消息还，如果验证通过返回。

I have a form that when you submit it, it sends the data for validation to another php script via ajax. Validation errors are echo'd back in a div in my form. A success message also is returned if validation passes.

的问题是，表单提交和验证成功仍显示之后。我想躲在成功后的股利。

The problem is that the form is still displayed after submit and successful validation. I want to hid the div after success.

所以，我写了这个简单的CSS方法的形式显示在页面调用时，工作正常。

So, I wrote this simple CSS method which works fine when called from the page the form is displayed on.

现在的问题是，我似乎无法通过调用返回code中的隐藏脚本。我可以返回HTML一样

The problem is that I cannot seem to call the hide script via returned code. I can return html like

echo "<p>Thanks, your form passed validation and is being sent</p>";

所以，我以为我可以简单地附和之后的另一行

So I assumed I could simply echo another line after that

echo "window.onload=displayDiv()";

里面的脚本标记（我不能在这里显示）...

inside script tags (which I cannot get to display here)...

和它会隐藏窗体DIV。

and that it would hide the form div.

这是行不通的。我假设的问题是，JavaScript是返回错误，而不是由浏览器PTED间$ P $ ...

It does not work. I am assuming that the problem is that the javascript is being returned incorrectly and not being interpreted by the browser...

我如何通过从我的验证脚本返回的数据调用网页上我的隐藏的脚本？我可以回显文本，但该脚本调用是无效的。

How can I invoke my 'hide' script on the page via returned data from my validation script? I can echo back text but the script call is ineffective.

谢谢！

这是在页面的形式...

This is the script on the page with the form...

我可以调用它来显示/隐藏的东西，如的onclick =displayDiv（），而在表单上，​​但我不希望用户调用这个...它被称为一个成功的验证结果当我写的结果返回给DIV ...

I can call it to show/hide with something like onclick="displayDiv()" while on the form but I don't want the user to invoke this... it has be called as the result of a successful validation when I write the results back to the div...

<script language="javascript" type="text/javascript">
    function displayDiv()
    {
        var divstyle = new String();
        divstyle = document.getElementById("myForm").style.display;
        if(divstyle.toLowerCase()=="block" || divstyle == "")
        {
            document.getElementById("myForm").style.display = "none";
        }
        else
        {
            document.getElementById("myForm").style.display = "block";
        }
    }
    </script>

PS：我使用的是mootools.js库表单验证，如果这个重要的语法。

PS: I am using the mootools.js library for the form validation if this matters for the syntax..

Ajax调用是：

window.addEvent('domready', function(){
$('myForm').addEvent('submit', function(e) {
new Event(e).stop();
var log = $('log_res').empty().addClass('ajax-loading');
this.send({
update: log,
onComplete: function() {
log.removeClass('ajax-loading');
}
});
});
});

股利ID日志是Ajax调用回文本（验证错误和成功消息）和装载图形显示

Div ID log is where the ajax call back text (validation errors and success message) and loading graphic appear

var response = "html\<script type=\"text/javascript\">alert(\"foo\");<\/script>html";
 var reScript = /\<script.*?>(.*)<\/script>/mg;
 response = response.replace(reScript, function(m,m1) {
     eval(m1); //will run alert("foo");
     return "";
 });
alert(response); // will alert "htmlhtml"
