Hi,

 

I want to change a background color of a read only variable of Catalog item. There is a reference variable name cost center in a requested item whose default background colour is grey.

Hello,

I don't think it will work without DOM manipulation which servicenow doesn't recommend. Also, always keep your script's UI type to 'All'. Please go through below threads

Hi @Siddharth4 ,

you could create a catalog ui catalog policy that does sets the values like this



function onCondition() {

 

document.getElementById('sys_display.IO:ae6c35dc3482adc0286558191d6651c4').style.backgroundColor="red";

 

document.getElementById('sys_display.IO:ae6c35dc3482adc0286558191d6651c4').readOnly = true;

 

}



you'll just have to get the ID=sys_display:IO:xxxxx (sysid) value is on the variable

 

which can be done using the google inspect element feature in chrome



<input class="questionsetreference" onkeyup="return acReferenceKeyUp(this, event)" onkeydown="return acReferenceKeyDown(this, event);" onkeypress="return acReferenceKeyPress(this, event)" ac_order_by="name" ac_columns="email" autocomplete="off" id="sys_display.IO:xxxxxx" title="" name="sys_display.IO:xxxxx" value="" onfocus="if (!this.ac) new AJAXTableCompleter(this, 'IO:xxxxxxx', '', '', 'sys_user');">
