I am facing a crisis here. I have a textbox, named businessInfo_businessAddress, which contains client's address loaded from the database when the page is loaded. I have a hidden field, named tracking-select-business-country-code
Uncaught TypeError: Cannot read property 'value' of null
I guess it must have something to do with variable autocomplete (just guessing). Anyway, what I need is that after the form finishes loading (ie. $(document).ready is called), google map api must be called with the value contained in the textbox businessInfo_businessAddress (for example: "Atlanta, GA, United States") and return the country code for hidden field tracking-select-business-country-code. I wonder how can I do that? Any idea? What change do I need to make in the code? Please help!!!! Thanks everyone.
How to call Google Map API in $(document).ready to get the country code? Please HELP!
in JavaScript
