java 字符串拆分字符串数组

java 字符串拆分字符串数组

用split();

if(associatedCheckMoreOldStr.length()>0){
      String[] tmp = associatedCheckMoreOldStr.split("_");
      associatedCheckMoreOld = new String[tmp.length];
      for(int i =0;i        System.out.println(tmp[i]);
       associatedCheckMoreOld[i] = tmp[i];
      }
     }

当拆分字符为|时，将拆分成一个个的字符数组，而不是字符串

javascript在拼接字符串时，要给associatedCheckMoreOldStr=“”，不然默认undifande在拼接的前面

 var associatedCheckMoreOldStr="";
   var majorCheckMoreOldStr="";
   var associatedCheckMoreNewStr="";
   var majorCheckMoreNewStr="";
   if(associatedCheckMoreOld.length != undefined)
   {
   for(var i=0;i    {
    if(associatedCheckMoreOld[i].value!=""){
    associatedCheckMoreOldStr+=associatedCheckMoreOld[i].value+"_";
    }
    if(majorCheckMoreOld[i].value!=""){
    majorCheckMoreOldStr+=majorCheckMoreOld[i].value+"_";
    }
   }
   }
