之前工作用的JavaScript比较多，总结了一下工具类，和大家分享一下，有不足之处还请多多见谅！！
1. 数组工具类（arrayUtils）

}
}
return arr;
};
object.join = function (arr,separator) {
return arr.join(separator);
};

if (arguments.length > 0) {
for (i = 1;i < arguments.length; i++) {
arr.push(arguments[i]);
}
}
return arr;
};

return arr.slice(start,end);
};
object.sort = function (arr,isDesc) {
if(isDesc){
arr.sort(function (a,b) {
return a<b?1:-1;
});
}else{

return a<b?-1:1;
});
}
return arr;
};

var hasTargetValue=false;
$.each(arr,function (index,item) {
if(item==targetValue){
hasTargetValue=true;
}
