防止回发

Question

I want to be able to prevent this postback without actually editing the HTML itself.

<a class="button campaign-button" id="ctl00_main_fastcheckout_FastCart_FastDiscount_lbDiscountCode" href="javascript:__doPostBack('ctl00$main$fastcheckout$FastCart$FastDiscount$lbDiscountCode','')"><span>OK</span></a>

Is there a default way of disabling postbacks perhaps on document load?

Thanks :)

Answer 1

You can always use return false .

OnClientClick="yourFunction(); return false;"

In js :

yourFunction(){
    //code
    return false;    
}

Answer 2

Try this Java script on your page

window.__doPostBack = function(eventTarget, eventArgument) {
return false;
};

But this is not the recommended way.
