how to abort action on submit using client script

[max_danielewicz]

Hi community,

i hope everyone is ok.

SITUATION

i created a catalogue client script that runs on change, and works. However, it should be running "on submit" instead, but i don't know how to make it work.

the client script calls a script include which returns a value and depending on the value i would display a message and abort the action or proceed.

PROBLEM

i cannot make it work !!

Here is the code (attached) used in the "on change" that i need to transform for the "on submit". could you pls help me to change it so it works on submit?

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var sdt = g_form.getValue("start_dt"); //Choose the field to add time from
var gt = g_form.getValue("guest_type");
var stayhs = g_form.getValue("hdays"); //The amount of time to add addtime
var addtype = 'hour'; //The time type. Can be second, minute, hour, day, week, month, year.

var ajax = new GlideAjax('ABCDateUtils');
ajax.addParam('sysparm_name','CarParkSpace');
ajax.addParam('sysparm_fdt', sdt);
ajax.addParam('sysparm_gtype', gt);
ajax.addParam('sysparm_addtype', addtype);
ajax.addParam('sysparm_stayh', stayhs);
ajax.getXML(doSomething);

function doSomething(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
//alert(answer);

if(answer == 'out') {
alert('Your hours selection has exceeded the amount of time you could stay for the day. Please select less hours.');
g_form.clearValue('hdays');

**should abort 
}
if(answer == null) {
alert('Unfortunately, there are not available spots for the selected date and time. Your request cannot be submitted.');
g_form.clearValue('hdays');
g_form.clearValue('start_dt');

**should abort
}
if(answer != null && answer != 'out') {
alert('Car spce ' + answer + ' will be reserved for you for the selected date and time. Please SUBMIT the form.');
}
g_form.setValue('spacename', answer);
** should submit
}
}

kind regards,

max

Hi,

To abort in client script just use the line below

return false;

Hi,

just use return false; whenever you want to abort submission.

Thanks,

The modified script would be:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var sdt = g_form.getValue("start_dt"); //Choose the field to add time from
var gt = g_form.getValue("guest_type");
var stayhs = g_form.getValue("hdays"); //The amount of time to add addtime
var addtype = 'hour'; //The time type. Can be second, minute, hour, day, week, month, year.

var ajax = new GlideAjax('ABCDateUtils');
ajax.addParam('sysparm_name','CarParkSpace');
ajax.addParam('sysparm_fdt', sdt);
ajax.addParam('sysparm_gtype', gt);
ajax.addParam('sysparm_addtype', addtype);
ajax.addParam('sysparm_stayh', stayhs);
ajax.getXML(doSomething);

function doSomething(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
//alert(answer);

if(answer == 'out') {
alert('Your hours selection has exceeded the amount of time you could stay for the day. Please select less hours.');
g_form.clearValue('hdays');

 return false;   //should abort 
}
if(answer == null) {
alert('Unfortunately, there are not available spots for the selected date and time. Your request cannot be submitted.');
g_form.clearValue('hdays');
g_form.clearValue('start_dt');

return false;  //should abort
}
if(answer != null && answer != 'out') {
alert('Car spce ' + answer + ' will be reserved for you for the selected date and time. Please SUBMIT the form.');
}
g_form.setValue('spacename', answer);
// do nothing
}
}

Hi Anil,

thanks for your suggestion.

i want to modify the client script to convert it to an "on submit" client script.
