I need a help like suppose I have a simple html ui page in ServiceNow. I want to include a client script. How to do this? I tried using
<script src="/sys_script_client.do?sys_id=123456"></script>
but it did not work
<html>
<body>
<h1>The input attribute</h1>
<script src="/sys_script_client.do?sys_id=123456"></script>
<form action="/action_page.php">
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname"/><br/><br/>
<label for="lname">Last name:</label>
<input type="text" id="lname" name="lname" disabled="disabled"/><br/><br/>
<input type="submit" value="Submit"/>
<a href="https://dev1234.service-now.com/x_1234_needlt_index2.do">link</a>
</form>
<p id="pid1">p1</p>
<button onclick="function1()">Click me</button>
</body>
</html>
document.getElementById("pid1").innerHTML="p1 is changed by client script of same page";
}
Calling an existing client script from a UI page doesn't really make sense. A saved client script is tied to a specific table and trigger. Your UI page doesn't have that limitation.
What you are likely wanting to do is call a script include from the UI page... That you can do using the GlideAjax method to call that specific script include.
Here's a link on details of running script include from UI page... ServiceNow UI Page GlideAjax
