Implementation method of dynamically generating form and submitting it in ajax way

Js code:

 var tempForm = document.createElement("form"); tempForm.action="http://localhost:8080/test/user"; tempForm.method="post"; document.body.appendChild(tempForm); //create a submit button var tempInput = document.createElement("input"); tempInput.type="hidden"; tempInput.name="method"; tempInput.value=methodName; //the parameter of method in the code of DispatchAction. tempForm.appendChild(tempInput); //submit the form tempForm.submit(); Ext.Ajax.request({ form:'intPayForm', method:'post', success:function(data){ alert(data.responseText); }, failure:function(){ } });

This writing method is supported in Ext 3, and other versions have not been tried yet.

The above implementation method of dynamically generating form and submitting it in Ajax is all the content I share with you. I hope you can give you a reference and I hope you can support Wulin.com more.
