In this video tutorial we will be taught how to write a function in java script to check if a string exists in a java script:
- At first the example code along with the content string and string is noted properly. And then the content is searched for ‘rose1’then it was not found.
- There were basically two functions : content and content to find. In the source content we will note the ‘content.indexf’and ‘content to find’. If the value is greater than 1 then the content is true or else it is false. Thus, we can find if a string exists in a string or not.
- In the method ‘on a button click’ .Here the source contains and the text contains are noted. If it is true then the content is not found. Thus, we can check if a string exists in a string in java script or not.
- Thus, if we enter some other name in the find string option and click on ‘search in content’ then it is not found.
