I am trying to search for a word in iframe and color it using angularjs and jquery. For jquery code i took help from @andrew stackoverflow. In Jquery code if condition is there, controller is not going inside if condition. please help me to solve the problem.
Here is my complete code, which contains angular code and jquery code.
Angular code is working just fine, in the console i am able to see all the consoles, first i am parsing the arrays and taking out only the string required to search in the jquery. After that i am using that search word to search in the the iframe. But i am facing some problem with the jquery code.

You can do it easily with Jquery, you can use this function on Javascript:
You only need to get the position of the word in the html of the iframe, that you can get with
$("#id-of the iframe")[0].outerHTML, and after insert in that position a span element with the colored style for the word.I maked a basic example with a Div that works in the same way that with an a iframe, you can see the example here:
