How to trigger a processing script in UI page through button

[ngo]

Hi Folks ,

I am creating a form in UI page and the fields on the form needs to be updated in Service now after click of a button on the page

I was able to do it via client script but it is taking some time and it is not the best practice

All I want is to trigger the processing script on the click of the button and then i will write my code inside it and not in client script

Thanks & Regards

Hi Nitish,

The processing script is run when you do a form submit. You can then get the input variables (e.g. text input named 'first_name' as variables in your processing script.

Example:

var gr = new GlideRecord('sys_user');

gr.first_name = first_name; // get value of first_name input variable.

// do other stuff

gr.insert()

Processing script can access the fields only when they are inside the <g:form> tags. See this link for more info

Hi Nitish,

The processing script is intended to execute server side after the form is submitted.   If you want to run the processing script you need to make sure your button has type="submit" as an attribute.  

Unfortunately, this forces you to refresh (or navigate away from) the form.   If you can't handle a refresh but you still need some code to execute server side, I'm afraid the processing script is not the right place to put it.   You should instead use a combination of GlideAjax in the client script and a script include server side.

I hope this helps.

Hi Dan

Thanks for your reply and thanks for your idea of using glideajax

I tried making my button type="submit" but was unable to make the processing script work , tried enclosing it in function and also without it but nothing seems to work

also the input variable in html will be directly available in it since gel works only in client side

example <div>Short Description: <input type="text" style="height:30px;" id="des" size="50" /></div>

var description = des ; will take the value from the text box and feed it to the variable

Please comment if I am wrong anywhere

Thanks
