Introduction:<\/strong><\/p>\n

Resco Mobile App is a boon for the Field Technicians; it\u2019s crisp, it\u2019s smooth and has a lot of functionalities that could ease the life of a Technician. Resco provides us Form Rules to perform many things in the face of onchange, onload and onsave event on the form.<\/p>\n

Limitations:<\/strong><\/p>\n

We could say, Resco Form Rules are more than sufficient for your core and advanced needs.<\/p>\n

But, there could be scenarios that are not simple to implement and cannot leverage the OOB Form Rules functionality.<\/p>\n

Workaround:<\/strong><\/p>\n

To leverage the OOB Form Rules functionality, we need to resort to the JavaScript option.<\/p>\n

Yes, we can have a JavaScript called\/triggered on the change of a field on the Form.<\/p>\n

The procedure to implement the JavaScript way is very simple, given that you know how to do that.<\/p>\n

Even when we had to implement the JavaScript approach, it took us a while before we could figure out the correct approach.<\/p>\n

The steps are pretty simple, as explained below:<\/p>\n

1.\u00a0We need to create an HTML that would be placed as an iframe on the form.<\/p>\n

2. The HTML should have a reference to the JSBRIDGE.js<\/p>\n

3. Then based on the onchange event described here<\/a>, create a function.<\/p>\n

4. Next, you need to call this function on load of the HTML page; this is the most important step.<\/p>\n

We initially tried using the $(document).ready, but it didn\u2019t work.<\/p>\n

But, after calling the function as below did the trick for us.<\/p>\n

<body onload=”onLoad();”><\/strong><\/p>\n

5. Once you have the HTML ready, upload the necessary files to the Offline HTML section of Resco, and on the form create an iframe.<\/p>\n

\"Call<\/p>\n

6. While creating an iframe, do not forget to uncheck the Delay Load.<\/p>\n

\"Call<\/p>\n

Note: Unchecking the Delay Load makes sure that the HTML is loaded as soon as the form is loaded and hence it facilitates the binding of onchange event.<\/em><\/strong><\/p><\/blockquote>\n

Conclusion:<\/strong><\/p>\n

Within few simple steps, you can easily have a JavaScript called\/triggered on the change of a field on the Form in Resco and leverage the OOB Form Rules functionality.<\/p>\n
