jquery Post在我的页面的这一部分不起作用

Question

I am trying to show an image by ajax-jquery.

this is part of my html:

<div id="searchFormResult1"></div>

<form action="#" method="post" id="searchForm" onSubmit="return false;">
    <input type="text" maxlength="10" id="searchid" name="searchid" class="searchstu" />
    <input type="submit" value="0" id="searchsubb" class="hidd searchsub" />
    <a href="#" id="link-2" onClick="sear(); return false;"></a>
</form>

the div tag is a place for returning php.

my jquery is like this and I put jquery inside the html page:

$("#searchsubb").click(function(){
$.post("parts/search.php", {searchid:$("#searchid").val()}, function(data){
    $("#searchFormResult1").html(data).slideDown();
});
});

also I have a php page that returning an image html tag:

something like this:

print "<img src='' /> and other thing"; 

but my returning value is not receiving.

I dont get any error in my browser and I believe the problem is not from my php.

I receive this error in chrome some times .

Error in event handler for 'undefined': INDEX_SIZE_ERR: DOM Exception 1 Error: Index or size was negative, or greater than the allowed value.

Answer 1

I believe your submitting the form at the same time you fire the ajax request.

Add return false to prevent the form submission.

$("#searchsubb").click(function(){
$.post("parts/search.php", {searchid:$("#searchid").val()}, function(data){
    $("#searchFormResult1").html(data).slideDown();
});
return false;
});

问题必须在PHP中，否则你会从ajax获得响应，来自$ .post触发器的第三个参数当ajax从parts / search.php获得响应时，尝试查看firebug中的响应标记，如果你没有一个是空或没有回应
