Question

I m new to jQuery and am having a couple problems with this code:

var theCommentId =   ;
var buildFormName =   ;

$( .comment_submit ).bind( click , function() {
    theCommentId = $(this).attr( this_id );
    buildFormName = ( #AddMessageForm_  + theCommentId);
}); 

alert(buildFormName);

This returns #AddMessageForm_1 (or 2 or 234 depending on what button is clicked). That part is working great.

But then I need to pass buildFormName in here so I can process multiple forms with different names. The form names are generated dynamically from an id number that s appended to addMessageForm

$(buildFormName).submit(function(e) {
    // process form data here...
    $.post( process.php , $(this).serialize(), function(msg) {
    }

The above returns no errors, but $this is empty and I can t create the db row from an empty $this! it works if I don t try to pass the variable buildFormName in there. example:

$( #addMessageForm_1 ).submit(function(e) {
    // process form data here...
    $.post( process.php ,$(this).serialize(),function(msg){
    }

罚款。我希望,我在这里没有简单的东西。任何帮助都受到高度赞赏。

感谢!

您应将提交书记员作为单独的职能,然后使用。引证。

$( .comment_submit ).bind( click ,function(){
    theCommentId = $(this).attr( this_id );

    buildFormName = ( #AddMessageForm_  + theCommentId);

    $(buildFormName).submit(formSubmitHandler);
}); 

function formSubmitHandler(){
   // process form data here...

   $.post( process.php ,$(this).serialize(),function(msg){

   }
}

Try replacing this with e.target, see if that helps.

$(buildFormName).submit(function(e) {
    // process form data here...
    $.post( process.php , $(e.target).serialize(), function(msg) {
}
