small jquery problem

[pradeepjain]

i am building a select based on the values in a text box .
like

$("#pincode").change(function(){
$.post("doctor_search.php",{ pincode:$("#pincode").val()} ,function(data){
$("#suggestions").html(data);
});
    });

when ever a error occurs when the form is submitted the select does not work as ajax is a change function . how to say to jquery tht do it if the value in the text box is not null also i.e trigger a event ??

Why not add a simple if condition which checks the value? If it's not empty. the request is made.

[pradeepjain]

hmm..yeah i thought of same logic..but i cld not write the if condition in jquery !! i am new to it !plzz can u show me the code !!only if condition?

[acoder]

Why not use regular JavaScript, except perhaps to reference an element? E.g.

if ($("#pincode").val() != "") {

[pradeepjain]

its something like this rite

if ($("#pincode").val() != "") {
$("#pincode").change(function(){
$.post("doctor_search.php",{ pincode:$("#pincode").val()} ,function(data){
$("#suggestions").html(data);
});
    });
}

I had written that code earlier only ! but did not work ! so i thought the code was wrong ! anyways will give it a try again and get back to you. thank you :)

[acoder]

No, that's not correct. Put the if statement inside the change function.

[pradeepjain]

but then error is other fields are discovered and errors are displayed again bcos of the

.change

i need to change the value in the pincode field for the jquery event to happen !!

[acoder]

So you want this to take place when the form is submitted even if there are errors?

[pradeepjain]

if the field has some value in it the event must be triggered !

[acoder]

Yes, but when? When should the check be made that there's some text in the field?

[pradeepjain]

when the user fills out the form 1st time its all okie .he fills the pincode thing so .change will work there . but say when the form has some errors and the same page is displayed with errors then the .change will not happen so i wanted to check if value is there in pincode then trigger the event !

[acoder]

When the same page is displayed with errors, is the page still the same (Ajax) or what it unloaded/reloaded?

I think it's best if you show the page where the problem occurs.
