用于下载pdf的IE中的预期对象错误

Question

我有下载pdf报告的功能。我为此创建了一个单独的js文件。无论Google Chrome中的任何问题，都会下载该报告。但它不会在Internet Explorer 11版本中下载。它显示错误“预期对象”。

var selectedValue = $(this).val();
	        if (selectedValue == 'VesselSummary') {
	        	
	        	var $grid=$("#vessel_tab_main"); 
	        	var DM = $grid.pqGrid("option", "dataModel");
	        	var data = DM.data;
	        	$("#optionforvessel").empty();
	        	for(var i=1; i<data.length; i++){
	        		var newOption = document.createElement("option");
	        		var name=data[i].vslName;
	        		var index=data[i].vslId;
	        		
	        		newOption.text = name;
	            	newOption.value = index;
	            	optionforvessel.appendChild(newOption);
	        	}

	        	$("#optionforvessel").show();
	        }else{
	        	$("#optionforvessel").hide();
}



function tpcDry(val,rowIndx){
  if(rowIndx!=0){
	vesselSubSummary.push({"selectedVslRuleName":toTitleCase(data3[val].poolRuleName)  ,"selectedVslRuleValue":data[rowIndx].tpc ,"selectedVslRulePoints":data2[rowIndx].tpcValue });
  }else{
     vesselSummaryAdditionalOne.push({"standardVslRuleName":toTitleCase(data3[val].poolRuleName),"standardVslRuleValue":data[rowIndx].tpc});
     vesselSummaryAdditionalTwo.push({"standardVslRuleName":toTitleCase(data3[val].poolRuleName),"standardVslRuleValue":data[rowIndx].tpc});
 }
 }

这是我正在使用的代码。这里面是if循环函数，它显示了预期对象错误。请帮帮我怎样才能解决这个问题？
