"Go" prevents pages from repeating commits

SB Saves the JavaScript script code and executes the script when the Submit button is clicked
StringBuilder sb = new StringBuilder ();
Guaranteed execution of validation functions
Sb. Append ("if (typeof (page_clientvalidate) = = ' function ') {if (page_clientvalidate () = = False) {return false;}};");
Click the Submit button to set the button's Disable property to prevent the user from clicking again, note that this is the JavaScript code
Sb. Append ("this.disabled = true;");
Submit with __doPostBack to ensure server-side click event Execution of the button
Sb. Append (this. Clientscript.getpostbackeventreference (This.btnsubmit, ""));
Sb. Append (";");
Setuistyle () is a JavaScript function that executes after clicking the Submit button, such as the ability to show the animation effect prompting background processing progress
Note Setuistyle () is defined in the ASPX page
Sb. Append ("Setuistyle ();");
Add the OnClick property to the Submit button
THIS.BTNSUBMIT.ATTRIBUTES.ADD ("onclick", sb.) ToString ());
