三.JS代码
window.onload = function () {
var user = ["../img/img_17.jpg"];
var num = 1;//判断左右
var portrait_position = 0;
var now = -1;//左右浮动
var send_btn = document.getElementById('send_btn');
var send_txt = document.getElementById('send_txt');
var chat_ul = document.getElementById('chat_ul');
var chat_span = chat_ul.getElementsByTagName('span');
var chat_img = chat_ul.getElementsByTagName('img');
send_btn.onclick = function () {
if (send_txt.value == '') {
alert("请不要惜字如金");
} else {
chat_ul.innerHTML += '<li><img src="../img/img_24.jpg"><span>' + send_txt.value + '</span>';
now++;
if (num==0) {
chat_span[now].className = 'spanright';
chat_img[now].className = 'imgright';
}
else {
chat_span[now].className = 'spanleft';
chat_img[now].className = 'imgleft';
}
send_txt.value = '';
// 内容过多时,将滚动条放置到最底端
/*contentcontent.scrollTop = content.scrollHeight;*/
}
}
}
num 消息显示在左边还是右边,根据后台请求来操作
