javascript - Loop through all text boxes in a form using jQuery

Question

I have a form which is laid out like a spreadsheet.

I want to validate the text in each textbox and if it's not numeric, change the background of the textbox and display a message.

I can do everything except for the looping part.

I'm guessing it's a for...each statement?

Answer 1

$('form input[type="text"]').each(function(){
        // Do your magic here
        if (this.value.match(/D/)) // regular expression for numbers only.
            Error();
});

If you got the form id:

$('#formId input[type="text"]').each(function(){
        // Do your magic here
});
