</form>

</div>

here I want to check the string “Invalid field” is present or not in that content. If it’s not present I want to do some other functionality.But I don’t know How to do this

Does any one know this ? Please help me ASPS.

Thanks in advance

Answer 1

if (addText.indexOf("Invalid field") != -1) { /* it's present */ }

// OR with regex

if (/Invalid field/.test(addText)) { /* it's present */ }

// OR with case-insensitve regex:

if (/Invalid field/i.test(addText)) { /* it's present */ }
