Make change fields read only based on Standard change template

[yamunapriya]

Hi All, 

Could you please help me with the following scenario:

We have to make certain fields of the change request read only for standard type change. The field values are populated based on the Standard change template (values are stored in the table std_change_template). If the value is autopopulated from template then we have to make read only. Otherwise the filed should be editable. 

Thank you

@Alberto Consonni  Thank you , but I need the fields to be filled in by the user in case there is no value populated from the template.

There are 2 fields 1. Mandatory on dictionary level  2. Nonmandatory

will the above workaround resolve the issue?

@yamunapriya I understood now, so in this case you should modify the client script Mark standard change fields readonly adding a condition there.

Please give it a try and let me know.

@Alberto Consonni : Can we create a separate client script or do we need to edit the existing one. 

The exisitnd client script to make fields read only is ;

function onLoad() {
var chgType = g_form.getValue("type");
var ga;
if (chgType == "standard") {
if (g_form.isNewRecord() || g_form.getUniqueValue() === -1 || g_form.getUniqueValue() === '-1'){
ga = new GlideAjax('StdChangeUtils');
ga.addParam('sysparm_name', 'ajaxFunction_getReadOnlyFieldsOnInsert');
ga.getXMLAnswer(markReadonly);
}
else {
ga = new GlideAjax('StdChangeUtils');
ga.addParam('sysparm_name', 'ajaxFunction_getReadOnlyFields');
ga.addParam('sysparm_sysId', g_form.getUniqueValue());
ga.addParam('sysparm_tableName', 'change_request');
ga.getXMLAnswer(markReadonly);
}
}
}

function markReadonly(answer){
if(answer){
var parsedAttributeNames = answer.split(',');
for(var i = 0; i < parsedAttributeNames.length; i++){
if(g_form.hasField(parsedAttributeNames[i]))
g_form.setReadOnly(parsedAttributeNames[i], true);
}
}
