字符串去重的一个实例分享

 
 var str = "aabdeegdcffdsf",
 result = [],
 tempStr = "";
 var removeDuplicate = function ( str ){
 var arr = str.split('');//把字符串分割成数组
 //arr.sort();//排序
 for(var i = 0; i < arr.length; i++){
 if(arr[i] !== tempStr){
 result.push(arr[i]);
 tempStr = arr[i];
 }else{
 continue;
 }
 }
 return result.join("");
 }
 console.log(removeDuplicate(str)); //abdegdcfdsf

var removeDuplicate = function ( str ){ var arr = str.split('');//把字符串分割成数组 //arr.sort();//排序 for(var i = 0; i <arr.length; i++){ if(tempStr.indexOf(arr[i])>=0){continue; console.log(1) }else{//console.log(2) result.push(arr[i]);
 tempStr+=arr[i];console.log(tempStr); } } return result.join(""); }

试了一下，运行结果如下：abdegcfds
