Js遍历Josn对象(内容对比页实现思路)

更好的遍历Josn的方法,利用jquery的each方法:

  var arr1 = [ "one", "two", "three", "four", "five" ]; 
  $.each(arr1, function(){ 
  alert(this); 
  }); 
  输出:one two three four five 

  var arr2 = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] 
  $.each(arr2, function(i, item){ 
  alert(item[0]); 
  }); 
  输出:1 4 7 

  var obj = { one:1, two:2, three:3, four:4, five:5 }; 
  $.each(obj, function(key, val) { 
  alert(obj[key]); 
  }); 
  输出:1 2 3 4 5 

 

  var obj = { "one": ["1", "2", "3"], "two": ["1", "2", "3"], "three": ["1", "2", "3"], "four": ["1", "2", "3"], "five": ["1", "2", "3"] };
$.each(obj, function (key, val) {
    alert(val[2]);
});
  写了几个例子,运行一下看看就明白啦!很简单吧!
