javascript - Internet Explorer 不会读取对象属性

Question

注释掉的部分在 IE 中不起作用，但在其他浏览器中起作用。

[query.outFields[1]] 上的 IE 错误声称它需要一个字符串或数字。任何想法为什么？关于如何让 IE 使用这些注释行有什么想法吗？

                             var attS = 
                            {
                                //[query.outFields[1]]: pin, 
                                //[query.outFields[0]]: vars[0], 
                                //[query.outFields[2]]: vars[5], 
                                //[query.outFields[3]]: vars[6],
                                PIN: pin, 
                                APN: vars[0], 
                                PARCELAREA: vars[5], 
                                AREATYPE: vars[6],
                                PARCELVER:working[0],
                                PERMITNUM:working[1],
                                ADDRESSID:working[2]
                            } 

如果您认为它会有所帮助，这是整个代码块..

                for(j =0;j<multiPermit.length;j++)
                {
                    var vars = multiPermit[j];
                    console.log(vars);
                    //center X
                    var x = vars[2];
                    //center Y
                    var y = vars[3];                                                
                    var pin = vars[4];
                    //console.log(pin);

                    //Delete source geometry for multi point from final data to ensure it's not represented twice.
                    for(l=0;l<inputInfo.data.length;l++)
                    {
                        temp = inputInfo.data[l];
                        if(temp.attributes[query.outFields[0]]==vars[0] && temp.x == x && temp.y==y)
                        {
                            inputInfo.data.splice(l,1);
                        }                              
                    }                        

                    //var Test=query.outFields[1];
                    //console.log(Test);
                    for(var i=0; i<zipArray.length;i++)
                    {
                        var working = zipArray[i];
                        if(working[0]==vars[0])
                        {          
                            var quickPush=inputInfo.data    

                            var newX = x;
                            var newY = y;


                             var attS = 
                            {
                                //[query.outFields[1]]: pin, 
                                //[query.outFields[0]]: vars[0], 
                                //[query.outFields[2]]: vars[5], 
                                //[query.outFields[3]]: vars[6],
                                PIN: pin, 
                                APN: vars[0], 
                                PARCELAREA: vars[5], 
                                AREATYPE: vars[6],
                                PARCELVER:working[0],
                                PERMITNUM:working[1],
                                ADDRESSID:working[2]
                            } 

                            //console.log(attS);

计算属性名称({ [likeThis]: "here"})是 EcmaScript 6 中的一项新功能，Internet Explorer 尚不支持。

您需要先创建对象，然后再添加变量字段。

 var attS = {
   PIN: pin,
   APN: vars[0],
   PARCELAREA: vars[5],
   AREATYPE: vars[6],
   PARCELVER: working[0],
   PERMITNUM: working[1],
   ADDRESSID: working[2]
 };
 attS[query.outFields[1]] = pin;
 // etc
