Display Info MSG on CHG request formwhen change tasks are active

[praveen47]

Hi All, 

I have a requirement change request have any active change tasks are presented in related list tab, need to display info message on Change form. 

I have written the below scripts, when checked using logs it is getting always return false.

Can some one help me on this.

Script Inlcude:

//  Display info message
	checkimpTask: function(parentChg) {
        var answer;
        var chgTask = new GlideRecord("change_task");
        chgTask.addQuery("change_request", parentChg);		
        chgTask.addQuery("change_task_type", "planning");
        chgTask.addQuery("active", "true");
        chgTask.query();
        if (chgTask.next()) {
			
            answer = 'true';
	} 
        return answer;
		
    },

 Client script:

Onload

table: change

function onLoad() {
    //Type appropriate comment here, and begin script below
    var cTask = new GlideAjax('StdChangeTaskUtils');
    cTask.addParam('sysparm_name', checkimpTask);
    cTask.getXML(chgTask);
}
function chgTask(response) {
    var Validation = response.responseXML.documentElement.getAttribute('answer');
    if (Validation == 'true') {
        g_form.showFieldMsg('Display comments');

    }
}

Thanks,

Praveen D.

@praveen47 Please update your script include as follows.

//  Display info message
	checkimpTask: function() {
        var answer;
        var parentChange = this.getParameter("sysparm_parent_change"); 
        var chgTask = new GlideRecord("change_task");
        chgTask.addQuery("change_request", parentChange);		
        chgTask.addQuery("change_task_type", "planning");
        chgTask.addQuery("active", "true");
        chgTask.query();
        if (chgTask.next()) {
			
            answer = 'true';
	} 
        return answer;
		
    },

Make sure that the script include has Client Callable checkbox checked.

Update the client script as follows.

function onLoad() {
    //Type appropriate comment here, and begin script below
    var cTask = new GlideAjax('StdChangeTaskUtils');
    cTask.addParam('sysparm_name', 'checkimpTask');
    cTask.addParam('sysparm_parent_change',g_form.getUniqueValue());
    cTask.getXML(chgTask);
}
function chgTask(response) {
    var Validation = response.responseXML.documentElement.getAttribute('answer');
    if (Validation == 'true') {
        g_form.showFieldMsg('Display comments');

    }
}

Hope this helps.

Hi Praveen,

Create a client callable script include and pass the change request sys id from the client script.

Make the following changes,

in the script include change

chgTask.addQuery("change_request", this.getParameter('sysparm_change_id'));	

in the client script add

cTask.addParam('sysparm_change_id', g_form.getUniqueValue());

you did not send the Parent Change sys_id in OnLoad Client script, add the sys_id in parameter in Glide Ajax and retrieve the parameter in Client callable script Include

Script Include:

//  Display info message
	checkimpTask: function() {
        var parentChg = this.getParameter('sysparm_parentChange');
        var answer;
        var chgTask = new GlideRecord("change_task");
        chgTask.addQuery("change_request", parentChg);		
        chgTask.addQuery("change_task_type", "planning");
        chgTask.addQuery("active", "true");
        chgTask.query();
        if (chgTask.next()) {
			
            answer = 'true';
	} 
        return answer;
		
    },

 Client script:

Onload

table: change

function onLoad() {
    //Type appropriate comment here, and begin script below
    var cTask = new GlideAjax('StdChangeTaskUtils');
    cTask.addParam('sysparm_name', checkimpTask);
   cTask.addParam('sysparm_parentChange', g_form.getUniqueValue());
    cTask.getXML(chgTask);
}
function chgTask(response) {
    var Validation = response.responseXML.documentElement.getAttribute('answer');
    if (Validation == 'true') {
        g_form.showFieldMsg('Display comments');

    }
}
