//需求:在页面上显示很多的用户信息。
//思路：产生很多的li标签，里面包括很多其他标签。然后跟换里面的数据。
//方法1：把li和他所有的子标签都当做ul的innerHTML属性。
//步骤：
//1.设置一个变量装字符串。
//2.利用for循环，产生很多的li和他的子标签。
//3.累加到字符串中。
//4.把字符串设置为ul的innerHTML属性。
// //1.设置一个变量装字符串。
// var ul = document.getElementsByTagName("ul")[0];
// var str = "";
// //2.利用for循环，产生很多的li和他的子标签。
// //个数不是我们决定的，而是数组长度决定。
// for(var i=0;i<users.length;i++){
// //3.累加到字符串中。
// str += '<li><a href="#" target="_blank"><img src="'+users[i].icon+'" width="48" height="48" alt="tdxy01"></a><p><a href="#" title="'+users[i].name+'" target="_blank">'+users[i].name+'</a></p></li>';
//
//// str += '<li>' +
//// '<a href="#" target="_blank">' +
//// '<img src="'+users[i].icon+'" width="48" height="48" alt="tdxy01">' +
//// '</a>' +
//// '<p>' +
//// '<a href="#" title="'+users[i].name+'" target="_blank">'+users[i].name+'</a>' +
//// '</p>' +
//// '</li>';
// }
// //4.把字符串设置为ul的innerHTML属性。
// ul.innerHTML = str;
//方法2：造一个li标签。然后把他内部的所有内容以innerHTML属性的方式翻入li中。然后每一个li都放入ul中。
var ul = document.getElementsByTagName("ul")[0];
//造很多的li标签。
for (var i = 0; i < users.length; i++) {
var newLi = document.createElement("li");
//为li添加内容
newLi.innerHTML = '<a href="#" target="_blank"><img src="' + users[i].icon + '" width="48" height="48" alt="tdxy01"></a><p><a href="#" title="' + users[i].name + '" target="_blank">' + users[i].name + '</a></p>';
//li放入ul中
ul.appendChild(newLi);
