vb.net - How to show javascript alertbox on button click event in asp.net webpage if textbox1.text=""? -

-

how show javascript alertbox on button click event in asp.net webpage if textbox1.text="" ?

what must attach script button's client click event. in script, check value of textbox1. if it's empty, show alert , return false prevent form submitting (prevent postback).

to so, in page_load, insert following:

if (!page.ispostback) {     string script = string.format("if (document.getelementbyid('{0}').value == '') {{ alert('textbox empty'); return false; }}", textbox1.clientid);     btnmybutton.attributes.add("onclick", script); }

of course, encapsulate script in reusable method, use jquery check value, big idea.
