第二次拆分不能工作

Question

無法將相同的字符串拆分兩次。我做錯了什麼？

 // my original string 
     var str = "Left,Right-broken at left side";  
     var ary = "Left,Right-broken at left side"; 

     //getting text after - (working fine) 
     var res = str.split("-").pop(); 
     $('#disc_comm_tlside_ed').empty(); 
     $('#disc_comm_tlside_ed').val(res); 

     // with this i can get text before -once again i need to splt by comma only 
     var myarrays= str.substr(0, str.indexOf('-')); 

     //even this also returning original string 
     var splt = ary.split(','); 

     // alert(splt) when i alert this getting full string 
     for(var i = 0; i < splt.length; i++) 
     { 
      //alert(myarray[i]); 
      $(this).find("option[value ='"+myarray[i]+"']").attr("selected",true); 
      $('.batch_ed').multiselect('rebuild'); 
     } 

最後返回原始字符串！

需要得到前和文字分隔拆分文本，

需要得到左右僅作爲陣列

編輯：添加代碼片段張貼在評論。

var elements = ""; 
      var batchnoe= ""; 
      $.each(data.response.frc_disloc, function (a,b){ 
       batchnoe = '.batch_ed'; 
       $(batchnoe).each(function(i, obj) { 
       var batch_splt = b.frac_side; 
       var myarray = batch_splt.split(','); 
       for(var i = 0; i < myarray.length; i++) { 
        $(this).find("option[value ='"+myarray[i]+"']").attr("selected",true); $('.batch_ed').multiselect('rebuild'); 
       } 
       }); 
      });

請檢查輸出的控制檯日誌。

  // my original string 
 
       var str = "Left,Right-broken at left side";  
 
       var ary = "Left,Right-broken at left side"; 
 

 
       //getting text after - (working fine) 
 
       var res = str.split("-").pop(); 
 
     
 
       $('#disc_comm_tlside_ed').empty(); 
 
       $('#disc_comm_tlside_ed').val(res); 
 

 
       // with this i can get text before -once again i need to splt by comma only 
 
       var myarrays= str.substr(0, str.indexOf('-')); 
 
     
 
       //even this also returning original string 
 
       var splt = myarrays.split(','); 
 
       console.log(splt); 
 
       // alert(splt) when i alert this getting full string 
 
       for(var i = 0; i < splt.length; i++) 
 
       { 
 
        console.log(splt[i]); 
 
        $(this).find("option[value ='"+splt[i]+"']").attr("selected",true); 
 
        //$('.batch_ed').multiselect('rebuild'); 
 
       }
