How to select an input element by value using javascript?

Question

I\'ve seen it\'s jquery equivalent:

$(\'input[value=\"something\"]\');

But how do you select it using pure javascript (no jQuery).

Answer 1

Something like this works:

function getCheckboxByValue(v) {
        var inputs = document.getElementsByTagName('input');
        for (var i = 0; i < inputs.length; i++) {
                if(inputs[i].type == "checkbox" && inputs[i].value == v) {
                        return inputs[i];
                }
        }
        return false;
}
(function testCheckbox() {
        getCheckboxByValue("1").checked = true;
})();

Using jQuery would be much better, though.
