滑块 JS 无法在 IE9 和旧版本上运行



我有这个页面 http://kreditmoney.ch/de/kreditantrag/index.php

右侧的滑块在IE9和旧版本中不起作用。我在IE11上修复了错误。

我假设错误出在这段代码中：.........

else {  
            this.fireEvent('onChange', this.step);
            this.bkg.style.clip = "rect(0px "+  (parseInt(this.drag.value.now[this.z]) +3)  + "px 10px 0px)"
.

.......

这是完整的代码：

    var SliderMoj = new Class({
options: {
    onChange: Class.empty,
    onComplete: Class.empty,
    onTick: function(pos){

我找到了这个问题的解决方案。
