jQuery $.post() + IE8

问题:

<script type="text/javascript" src="/scripts/jquery-1.6.2.min.js"></script> 
<script type="text/javascript" src="/scripts/jquery.form.js"></script> 

<script type="text/javascript"> 
$(document).ready(function(){
$("#SendReply").click(function(){                                      
    $(".error").hide();
    var hasError = false;
    var pathname = window.location.pathname;
    var random = Math.random();

    var messageVal = $("#InquiryResponse").val();
    if(messageVal == 'Type your response in this space ...') {
        $("#InquiryResponse").after('<span class="error"><br><br><font color="red">You forgot to type your response to the inquiry. Please type it in the above space and submit again.</font><br></span>');
        hasError = true;
    }


    if(hasError == false) {
        $(this).hide();
        if (jQuery.browser.msie != true) {
        $.post( "",
            { Detail: messageVal},
                function(data) {
                    //alert("For non IE");
                    $("#InqRespForm").slideUp("slow", function() {                 
                         $("#InqRespForm").before('<h1>Success</h1><p><font color="green">Your message has been sent.</font></p>');                             

                });
        });
        }
        if (jQuery.browser.msie == true) {
            jQuery.ajaxSetup({async:false});

            $.post( pathname , { Detail: messageVal},function(data)
                {

                    $("#InqRespForm").width($("#InqRespForm").parent().width()).slideUp("slow");
                    $("#InqRespForm").before('<h1>Success</h1><p><font color="green">Your message has been sent.</font></p>');                  
                });
            jQuery.ajaxSetup({async:true});         
        }   


    }

    return false;
});                        
});
</script> 





<form action="" method="post" id="InqRespForm" name=InqRespForm>
Reply to the above Inquiry : <br/>
<textarea rows="7" name="Detail" id="InquiryResponse" cols="60" colspan=2>Type your     response in this space ...</textarea>
<br/>

<input id="SendReply" name="Send" type="submit" value="Send Response" alt="Reply to  Inquiry" /> 

</form>

On form submit, I send an email out. Which works on FF, Chrome etc. But I've gone bald trying to make this work in IE8. I will buy you beer if you can point me to a solution.

回答1:

I figured it out. Im going to post the solution here in case it helps someone in future. The problem was with the url i was posting to. My url was a parameterised url and I was using a wrong syntax/format all along. The IE and non IE separation is not really needed. The answer lies in extracting the various components of the current url and pass it in $.post via the "data" array. Thanks for your inputs. Working code below:

<script type="text/javascript" src="/scripts/jquery-1.6.2.min.js"></script> 
<script type="text/javascript" src="/scripts/jquery.form.js"></script> 
<script type="text/javascript" src="/scripts/jquery.url.js"></script>
<script type="text/javascript"> 
$(document).ready(function(){
$("#SendReply").click(function(){                                      

    $(".error").hide();
    var hasError = false;
    var pathname = window.location.pathname;
    var random = Math.random();
    var kar_ = $.url.param("kar"); 
    var obj_ = $.url.param("obj");
    var me_ = $.url.param("me");


    var messageVal = $("#InquiryResponse").val();


if(messageVal == 'Type your response in this space ...') {
    $("#InquiryResponse").after('<span class="error"><br><br><font color="red">You forgot to type your response to the inquiry. Please type it in the above space and submit again.</font><br></span>');
    hasError = true;
}


if(hasError == false) {
    $(this).hide();

    $.post( "inqdetails.asp",
        { Detail: messageVal, kar: kar_, obj: obj_, me: me_},
            function(data) {

                $("#InqRespForm").slideUp("slow", function() {                 
                     $("#InqRespForm").before('<h1>Success</h1><p><font color="green">Your message has been sent.</font></p>');                             

            });
    });

}

return false;
});                        
});
</script> 

回答2:

Why are you doing this: jQuery.browser.msie ????

There is almost never a reason to detect the browser! And I can see absolutely nothing in your code that requires knowing what the browser is.

回答3:

Put this line within your HTML just after the <head> tag starts

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

It will work for IE8+

回答4:

$.post( "", ... ) might have caused the problem. I found that it works in most browsers except IE.

Rather use $.post(window.location, ... ) to post to the same page.
