JavaScript 表单 Submit() 完成

Question

Is there a way to call the javascript form submit() function or the JQuery $.submit() function and make sure that it completes the submit process? Specifically, within a form, I am trying to submit a form within an IFrame. From the parent form, I am submitting the IFrame with the following code...

document.frames.IFRAME_Items.document.forms[0].submit();

The parent form then saves and closes. However, currently the IFrame is not completing the post before the parent form saves and closes. Is there any way using a JQuery callback or something in JavaScript to ensure this submit process completes before the parent form closes?

Answer 1

Best what you can do is to submit the iframe's form asynchronously with help of jQuery Form plugin . This way you can wait until the response is returned. It also provides a success callback handler which you can use to submit the parent page's form.

Answer 2

<form onsubmit="return controlParentForm();" id="parentForm">
...
</form>

JS:

var controlSubmitParentForm = 0;
function controlParentForm(){

   var ret = false;

   if (controlSubmitParentForm==0){

     controlSubmitParentForm = 1;
     document.frames.IFRAME_Items.document.forms[0].submit();
     setTimeout(controlParentForm, 200);

   }
   else if (controlSubmitParentForm==1){

     if (document.frames.IFRAME_Items.document.readyState=="complete"){
        controlSubmitParentForm = 2;
        document.getElementById("parentForm").submit();
     }
     setTimeout(controlParentForm, 200);

   }
   else if (controlSubmitParentForm==2){
       // controls for "parentForm"
       ret = true;
       controlSubmitParentForm = 0;
   }

   return ret;

}
