How to update only one field using UI action

[ChaitanyaKanuri]

Hi ,

I am trying to create an UI action to update only one field. I tried using the below code 

function saveDesc() {
    var desc = g_form.getValue('description');
    g_form.setValue('description', desc);
    gsftSubmit(null, g_form.getFormElement(), 'save_dec'); 
    action.setRedirectURL(current);
}

 Action Name  : save_dec

I am bale to save if i added the value of the description in the setvalue method. But if I am trying to get and set it is not working as expected. and after this script the page should be redirected to the same form page.

 

Can someone help me out.

Thanks.

Hi , Try this in your UI Action code

function saveDesc() {
    var desc = g_form.getValue('description');
    g_form.setValue('description', desc);
    gsftSubmit(null, g_form.getFormElement(), 'save_dec'); 
}
if(typeof window == 'undefined')
runBusRuleCode();

//Server-side function
function runBusRuleCode(){
current.update();
gs.addInfoMessage('You did it!'); //testing
action.setRedirectURL(current);
}

You should verify if any of the values in form are modified or not, if yes then clear the value.

I got the solution,

Instead looking for client side solution we can do it via server scripting via GlideRecord.

current.update is updating all the fields. so using below code we can get the solution.

var gr = new GlideRecord('incident');
gr.addQuery('sys_id',current.sys_id);
gr.query();
while(gr.next()) {
gr.description = current.description;
gr.update();
} 
action.setRedirectURL(current);
