How can I check the length of in String in JavaScript? Here is a small code example:
if(value != null && value != "" && value.length !== 10 && !value.match(/^\d*$/)){
// do something
}
The expression 'value.length !== 10' doesn´t work. A String must contain at least 10 characters. How can I solve this problem?
Instead of match, test can be used with proper regex \d{10,}.
if (value && /^\d{10,}$/.test(value.trim()))
\d{10} the , after 10 says that at least 10 characters(digits here), you can remove , to match exact 10 charactersTo Get the string length of a value for example:
var value="This is a string";
var string_length=value.length;
/*The string length will result to 16*/
Hope this helps
var regex = new RegExp(/^\d*$/),
value = $.trim("1234567890");
if (value.length >= 10 && regex.exec(value)) {
// correct
} else {
// incorrect
}
