Hi again! I've been breaking my head with this, I have this custom validation that I know for a fact is getting the right value from the data_read (true or false) but since ajax is asynchronous the validation fails to get the value...
I saw in a lot of posts recommendations about using ajax to run a data_read but even if I use "async:false" the value is not returned hence the validation fails, I don't know any other way to fetch data from the db to a js function... all I need is to check if the string written by the user is already in the db to prevent a duplicate, (I know this could be done on the submit but that's not the idea)...
Any suggestions?
😲😲😲 HELP PLEASE!!! 😲😲😲
jQuery.fn.form.settings.rules.fmnem = function(value){
var clientx = jQuery("select#client option:checked").val();
jQuery.ajax({
url: '{url:search}&tvout=view',
data: {client:clientx, nem:value},
success: function(result){
console.log("Return: "+result);
return result;
}
});

jQuery.fn.form.settings.rules.customfn= function(value, param){
var res = true; <---- Declare your result here before your ajax call
jQuery.ajax({
url: '{url:validate}&tvout=view',
async:false, <--- make sure async is false
type: "POST",
data: {val:value},
success: function(result){
res = true;
},
fail: function(result) {
res = false;
}
});
return res; <--- Return your result here
};
Hey Healy!! Sorry I didn't answer before! been away from the keyboard for a while, I really appreciate your help, you are awesome! but the problem is that browsers don't support "async false" because it may cause a hangup, so it seems I'm a little bit screwed, guess I'll just stick to the submit validation or try a third party validation script.
Many many thanks for your goodwill!
Many many thanks for your goodwill!
It worked for me
Post your current code, including the code you're using the bind the event and your event code.
My wrong! it works, just needed a slightly different logic approach, damn this was exhausting! lol...
Again many many thanks!
