IE 11 Ajax错误-“ SCRIPT65535：参数不可选”

Question

The code below works in every browser except IE, following an error message "SCRIPT65535: Argument not optional" .

function _getChart(){

    $('.series-data').remove();

    var itm = window.item;
    var tp = window.type;
    var ord = window.order;
    var xd = window.xdata;
    var yd = window.ydata;

    var dt = {superAwesomeTypeNotIEvar : tp,
              superAwesomeItemNotIEvar : itm,
              superAwesomeOrderNotIEvar : ord,
              superAwesomeXdataNotIEvar : xd,
              superAwesomeYdataNotIEvar : yd,
              superAwesomeCharHeightNotIEvar : $('.charts-wrapper').height()};

    $.ajax({

        url: "ajax/data.php",
        cache: false,
        data: dt,
        dataType: "json",
        success: function(data) {
           // Some fcs

As you can see I already tried renaming all the parameters to something that IE is not likely using for itself (eg the removeFilter story).

This is what the function looked like originally

function _getChart(){ 

    $('.series-data').remove();

    $.getJSON('ajax/data.php', {
        type : window.type,
        item : window.item,
        order: window.order,
        xdata : window.kurtosis,
        ydata : window.range,
        chartHeight : $('.charts-wrapper').height()}, function(data) {

If I set the dt array to just {} it all works, otherwise the error message above is shown.

SCRIPT65535: Argument not optionalFile: jquery.js, Line: 4, Column: 13144

jQuery non-min file line where the error appears

jQuery.param = function( a, traditional ) {
    var prefix,
    s = [],
    add = function( key, value ) {
        // If value is a function, invoke it and return its value
        value = jQuery.isFunction( value ) ? value() : ( value == null ? "" : value );
        s[ s.length ] = encodeURIComponent( key ) + "=" + encodeURIComponent( value );
    };

Why?

Answer 1

For what it's worth, in my case it was an improperly formed value for 'data'. Try checking dt in a debugger and making sure that it is the right data-type.

Answer 2

Add below code in ajax

  , cache: false
  , processData: false  // tell jQuery not to process the data
  , contentType: false  // tell jQuery not to set contentType

And try it again.

$.ajax({

    url: "ajax/data.php",
    cache: false,
    data: dt,
    dataType: "json",
    cache: false,
    processData: false,  // tell jQuery not to process the data
    contentType: false,  // tell jQuery not to set contentType
    success: function(data) {

// Some fcs

Not sure if this will help, and I know you've already tried $.getJSON, but perhaps this would make IE 11 happier:

$.post('ajax/data.php', dt, function(data) {
    // do something with data
},'json');

Alternately, you could try using $.get instead. That is missing the "cache:false" parameter, but I don't believe that's a bad thing. Using it doesn't actually mean all browsers will comply.
