replacement for document.all.sort.length

function ShowSortArrows() {
            for ( var i = 0; i < document.all.sort.length; i++ ) {
                document.all.sort[i].style.display = "none";
                document.all.sort[i].style.visibility = "";
            }
            if (iSortByColumn!=1) {
                if (strSortType=="ASC") {
                    document.all.sort[(iSortByColumn*2)-4].style.display="inline";
                } else {
                    document.all开发者_StackOverflow中文版.sort[(iSortByColumn*2)-3].style.display="inline";
                }
            }
        }

This is not supported in new browsers, so I need replacement.

Based on what you showed sort can be 2 things.

1. a <form> with the name or id sort
2. a collection of form elements named sort

The solutions for these situations are:

(1)

var sort = document.getElementById("sort");
var elements = sort.getElementsByTagName("input");

(2)

var input = document.getElementsByTagName("input");
var elements = [];
for (var i = 0; i < input.length; i++) {
  if (input[i].name === "sort") {
     elements.push(input[i]);
  }
}

Then the elements array will contain what you would get with the old-fashioned document.all.sort

It basically depends on what sort is (no HTML shown). It's not a valid HTML tag and there appear to be more than one per page so I'll assume it's a class name :-?

for ( var i=0, len=document.getElementsByClassName("sort").length; i<len; i++) {
}
