question about Page_ClientValidate() function

[Bob]

Hi,

i know what the javascript function Page_ClientValidate() function does:
tests if all controls meet asp.net validation criteria. This function is
provided by asp.net.
But how can a browser (and escpecially firefox, netscape ..) understand that
function, because it's not pre-programmed in the browser like the base
javascript code.

Thanks
Bob

All what the function does is defined in ASP.NET's client-side validsation
library which is loaded to the browser by ASP.NET when a page needing
validation controls is requested.

Starting in ASP.NEt 2.0 these functions (there are quite a alot of them)
have been written in cross-browser compatible way so they work in all modern
browsers.

For example Page_ClientValidate

function Page_ClientValidate(validationGroup) {
Page_InvalidControlToBeFocused = null;
if (typeof(Page_Validators) == "undefined") {
return true;
}
var i;
for (i = 0; i < Page_Validators.length; i++) {
ValidatorValidate(Page_Validators[i], validationGroup, null);
}
ValidatorUpdateIsValid();
ValidationSummaryOnSubmit(validationGroup);
Page_BlockSubmit = !Page_IsValid;
return Page_IsValid;
}

E.g down to the bottom these functions are just javascript accessing DOM
etc. E.g that base javascript.
