Show/hide the submit button on catalog item form based on select box

[Are Kaveri]

Hi,

we have the below scenario for one of our client.

based on employee type we need to show submit button to submit the request on service portal.

for this I have written client script on onload. But not understanding how to achieve this

if(g_form.getValue(employee_type) == ‘full time’){
show submit button

}else {don’t show}

please help me with the scripting

@Ankur Bawiskar  @Harish KM  helped .now working expected.

did isolated script to false.

in script

function onLoad(){
var emptype = g_form.getValue(‘employee_type’);

if(emptype != ‘full time’){

var z = this.document.getElementsByClassName("btn btn-primary btn-block ng-binding ng-scope");

        z[0].style.display = 'none';

}
}
