如何使用javascript转换特殊字符及其实体名称（如＆与＆）

Question

I have small requirement, have JSON data and I would like to convert all specialChars with escapeChars , I tried with following code but it throws an error like Object doesn't support property or method 'split' , please share me your ideas.

function applyEscapeChars()
                {                              
                            var str = { "aaData": ["dummy < data","ampersand&aaa","2015-02-16","2015-02-16",470.5,"xyz",1,0,"","Error: 1 Invalid format/sample","---"]}                            
                            var specialChars = new Array();
                                specialChars[0] = "&";
                                specialChars[1] = "\"";
                                specialChars[2] = "'";
                                specialChars[3] = "<";
                                specialChars[4] = ">";
                                var escapeChars = new Array();
                                escapeChars[0] = "&amp;";
                                escapeChars[1] = "&quot;";
                                escapeChars[2] = "&apos;";
                                escapeChars[3] = "&lt;";
                                escapeChars[4] = "&gt;";

                                for (var i =0; i < specialChars.length; i++ )
                                {                             
                                         str = JSON.stringify(str ).split(specialChars[i]).join(escapeChars[i]);                                             
                                }
                                //alert(str);

                                return str;

                }

Now everything is working fine except less than symbol(<)

Is it ok for you to let the browser do the html encoding?

function htmlEncode(value){
  //create a in-memory div, set it's inner text(which jQuery automatically encodes)
  //then grab the encoded contents back out.  The div never exists on the page.
  return $('<div/>').text(value).html();
}

It's taken from HTML-encoding lost when attribute read from input field
