onClick function in UI page

[ryadavalli]

I have a UI page, I have a button, which upon click call the client script and pass the context sysapproval record to client scrim. How can I do that?

Not sure if I follow you but lets try 😃

if you got a url like: .....service-now.com/mypage.do?sysparm_id=42354334543m5n4352h2423

On the UI page you can do something like

<g:evaluate var="myvariable">

var sysparm_id = RP.getParameterValue("sysparm_id");

                    sysparm_id;

</g:evaluate>

Then you can throw that into a hidden input:

<input type="hidden" id="kb_article" name="kb_article" value="${myvariable}"/>

And from client script:

var article= gel("kb_article").value;

Sorry about not changing the names/variables to something clever 😃 To tired

HEy Goran,

Thanks for the help !

Actually I have 2 buttons on UI page (change form change tasks)

change task 1 - Button 1

change task 2 - Button 2

Upon click I want to get the change task 1 assignment when user clicks on the button 1 and change task 2 assignment grp when button 2

I have <td style="text-align:center"><button class="getAssgnGrp" onclick="myFunction('${current.sys_id}')"><img src="image.gif"></img></button></td>

Is this the correct way and how to get the value in client script

client script:

function myFunction(test){

    alert("Hello == "+test);

}

I think I got it. I was passing some wrong value.. Now I get the values.

Yea.. you can put it like that as well. Then you don't need the hidden input either.

Just so I understand. You got 2 buttons which would go too two different   tasks.

If I think I understand you, you can't use "current" as in other scripts.

I would have made the buttons like this:

<td style="text-align:center"><button class="getAssgnGrp" onclick="myFunction('${taskone.sys_id}')"><img src="image.gif"></img></button></td>

<td style="text-align:center"><button class="getAssgnGrp" onclick="myFunction('${tasktwo.sys_id}')"><img src="image.gif"></img></button></td>

Then above that code you need something simular to this:

<g:evaluate>

//Fetch task one

var taskone = new GlideRecord('change_request');

taskone.get('number','CHG002133');

</g:evaluate>

<g:evaluate>

//Fetch task two

var tasktwo = new GlideRecord('change_request');

tasktwo.get('number','CHG002134');

</g:evaluate>

Then the client script like you did.

The g:evaluate for you is abit more dynamic, but I think you understand what I'm trying to "say" 😃
