js二维数组遍历,select选中状态，设置input默认值

//方案3.2恢复默认值
var array32=new Array();
     array32 =[
     ['show',10,'plan3_2_1'],['show',10,'plan3_2_2'],['show',120,'plan3_2_3'],['show',120,'plan3_2_4'],

     ['0',0,'plan3_2_17']
     ];
  for(var i=0;i<array32.length;i++){
    var array32_TR=new Array();
     array32_TR=array32[i]; 
     for(var j=0;j<array32_TR.length;j++){
      //设置select的选中状态
       var select = document.getElementById(array32_TR[2]+"_select");
         for(var k=0;k<select.options.length;k++){
          if(select.options[k].value==array32_TR[0]){//数组的第一项都是选中状态
         select.options[k].selected=true;
          }
