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

If you want all elements by ID you can use

function getElementsById(elementID){
    var elementCollection = new Array();
    var allElements = document.getElementsByTagName("*");
    for(i = 0; i < allElements.length; i++){
        if(allElements[i].id == elementID){
            elementCollection.push(allElements[i]);
        }
    }
    return elementCollection;
}
