JQuery `live()` and `submit()` problem
提问by Nick Craver
I wanna do something like this, but this one looks like happing for infinite times.
我想做这样的事情，但这个看起来像是发生了无限次。
$("form").live("submit", function() {
if($(this).attr('action') != "ajax"){
$(this).submit();
return true; // even i do this!! but form is NOT submited!!
}
else { /* doing the ajax stuff! */ }
});
in Chrome and Firefox after a while the form gets submitted, something like 10seconds and in IE it crashes !
一段时间后，在 Chrome 和 Firefox 中，表单被提交，大约 10 秒，而在 IE 中它崩溃了！
I know when i say form.submit means that i am submitting this and get called function again and again, how can i avoid this ?
我知道当我说 form.submit 意味着我正在提交这个并一次又一次地被调用函数时，我该如何避免这种情况？

By fring .submit()again, which bubbles back to the .live()handler, you're causing an infinite loop, instead you want to call the native form.submit()method here, like this:
.submit()再次fring返回到.live()处理程序，您将导致无限循环，而不是您想在form.submit()此处调用本机方法，如下所示：
$("form").live("submit", function() {
if(this.action != "ajax") {
this.submit();
}
else { /* doing the ajax stuff! */ }
});
Also .actionis a native DOM property, you can access it that way...not need for the jQuery overhead here.
也是.action本机 DOM 属性，您可以通过这种方式访问它……这里不需要 jQuery 开销。
