how to clear the field value

[Santosh Kallim1]

I have PFA, below fields, I have achieved this scenario through Ajax.

u_planned_outage_start
u_planned_outage_end
u_outage_duration

Now I need to achieve 

1. if old value  to new value  (u_planned_outage_start) then u_outage_duration field should be clear
2. if old value  to new value  (u_planned_outage_end) then u_outage_duration field should be clear
3. if any one field u_planned_outage_start or u_planned_outage_end empty then  u_outage_duration field should be clear

This must be client validation , 

Tried onchange but no luck, any help?????

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

//Type appropriate comment here, and begin script below
var Outageduration = g_form.getValue('u_outage_duration');
if(oldValue == newValue){

g_form.clearValue('u_outage_duration',' ');
}
}

I need to add few more condition in this, if there is no value in  u_planned_outage_start/u_planned_outage_end then u_outage_duration filed should get clear ...

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

var plOutstrt = g_form.getValue('u_planned_outage_start');
var plOutend = g_form.getValue('u_planned_outage_end');

var ajax =new GlideAjax('TSE_Outage_Duration_Calculation');
ajax.addParam('sysparm_name','durCalc');
ajax.addParam('sysparm_strt',plOutstrt);
ajax.addParam('sysparm_end',plOutend);
ajax.getXMLWait();
var answer = ajax.getAnswer();

//alert('answer ' +answer);
g_form.setValue('u_outage_duration', answer);

//Type appropriate comment here, and begin script below
}

HI,

You will need two OnChange script one onload script to check if anyone field is blank or not. One on Start and one on End.

Example:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

//Type appropriate comment here, and begin script below
var Outageduration = g_form.getValue('u_outage_duration');
if(oldValue == newValue){
g_form.clearValue('u_outage_duration'); You used in wrong way.
} 
}

Write Onload script to see if the Start and end date is blank or not. If yes then clearOutage.

Thanks,
Ashutosh

Create 2 onchange client scripts on u_planned_outage_start and u_planned_outage_end.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

if(newValue ===""){

  g_form.clearValue('u_outage_duration');
}

//Type appropriate comment here, and begin script below
if(oldValue == newValue){
g_form.clearValue('u_outage_duration');
}

}

For 3rd field, create a onload client script (if yu want to clear on load) or else write the same script on submit (if you want to clear it during submit)

function onLoad() {
//Type appropriate comment here, and begin script below
var outage_start = g_form.getValue("u_planned_outage_start");
var outage_end = g_form.getValue("u_planned_outage_end");
if(outage_start==="" ||outage_end===""){
g_form.clearValue('u_outage_duration');
}
}
