How to get view name from the portal using client script ?

[Virendra K]

Hi All,

I am opening Preapproved change request from the portal. I have written the Onchange client script on 'planned start date' field where I want capture the name of the view name from below url which should only work when Preapproved change request is opened. There are few suggestions to use "var view = getView()" but I can see the java browser error saying "its not defined"

How I could get the view name from below url or put such a constraint in client script so that defined code only should work when Preapproved change request is selected ?

Portal url :

https://demotest.service-now.com/change?id=preapproved_form&table=change_request&sys_id=-1&view=sip_preapproved&spa=1  

Thanks,

Virendra

Hi I believe the following code should help. You can write this code on onLoad client script.

var gUrl = new GlideURL();

gUrl.setFromCurrent();

var value = gUrl.getParam("view");

alert(value);

I have found the answer for this(link is given below).

https://servicenowguru.com/client-scripts-scripting/parse-url-parameters-client-script/

We can use fetch the parameter from the url using below code. 

//call /place below 2 lines in client script

var myparm = getParmVal('view');  // write any parameter name. example like sysparm_view , sys_id etc

g_form.addInfoMessage('view name '+ myparm );

//call /place below function within client script ( This is for portal fetch) 

function getParmVal(name) {  

    name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");  

    var regexS = "[\\?&]" + name + "=([^&#]*)";  

    var regex = new RegExp(regexS);  

    var results = regex.exec(top.location);  

    if (results == null) {  

        return "";  

    } else {  

        return unescape(results[1]);  

    }  

}

This is one of the ways of doin it by manually parsing the string. Try this once I think this will work on portal

var url = top.location.href;

    var value = new URLSearchParams(url).get("view");

So the glideUrl doesn't works on portal but this will.
