Question

I’m using Unicode value ‘✔’ to display a tick mark in text area.

Now I need to fetch the value in text area and need to check whether symbol is present in that?

When I’m fetching the text area value I’m getting a checkbox without tick like symbol instead of tick symbol.

How can I compare this Unicode value is exist or not?

// Not working.
if( document.getElementById('location').value.charAt(0) == '&#10004')
    alert("symbol');

Your problem is that ✔ is an HTML entity that represents ✔ in HTML but it is just a string in JavaScript. In JavaScript you’d want '✔' (the raw character) or '\u2714':

if(document.getElementById('location').value.charAt(0) == '\u2714')
    alert("symbol");
else
    alert("not there");

The HTML &#....; notation uses decimal numbers, the JavaScript '\u....' notation uses hexadecimal. Converting 10004 to hexadecimal yields 2714. You can also use &#x....; in HTML if you want to use hexadecimal there as well, for example ✔ is ✔. Using just hexadecimal is probably easier than dealing with the base conversions.
