How can I get the first three letters of a string in JQuery?
For example: Turn cat1234 to cat
778
Use the string. slice() method to get the first three characters of a string, e.g. const first3 = str. slice(0, 3); . The slice method will return a new string containing the first three characters of the original string.
var header = $('. time'+col). text(); alert(header);
You should use the charAt() method, at index 0, to select the first character of the string. NOTE: charAt is preferable than using [ ] (bracket notation) as str. charAt(0) returns an empty string ( '' ) for str = '' instead of undefined in case of ''[0] .
You can also remove the first character from a string using substring method. let input = "codehandbook" function removeCharacter(str){ return str. substring(1) } let output = removeCharacter(input); console. log(`Output is ${output}`);
No jQuery needed! Just use the substring method:
var name = "cat1234" var variable2 = name.substring(0, 3); Use .slice(start, end) with start and end values:
var str = 'cat1234'; document.body.innerHTML = str.slice(0, 3);With javascript you can use a regular expression with .match() method to exclude the number and get the string value.
var str ='cat1234', rg = /[a-zA-Z]+/g, ns = str.match(rg); document.body.innerHTML = ns[0];If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
