4.JS代碼

(1).提交評論:提交評論的a標(biāo)簽按鈕引用了樣式comment-submit，在其點(diǎn)擊事件中進(jìn)行ajax操作

$('body').delegate('.comment-submit','click',function(){

varcontent=$.trim($(this).parent().prev().children("textarea").val());//根據(jù)布局結(jié)構(gòu)獲取當(dāng)前評論內(nèi)容

$(this).parent().prev().children("textarea").val("");//獲取完內(nèi)容后清空輸入框

if(""==content){

alert("評論內(nèi)容不能為空!");

}else{

varcmdata=newObject();

cmdata.parent_id=$(this).attr("parent_id");//上級評論id

cmdata.content=content;

cmdata.nickname="游客";//測試用數(shù)據(jù)

cmdata.head_pic="/Public/images/default.jpg";//測試用數(shù)據(jù)

varreplyswitch=$(this).attr("replyswitch");//獲取回復(fù)開關(guān)鎖屬性

$.ajax({

type:"POST",

url:"/index.php/home/index/addComment",

data:{

comment:JSON.stringify(cmdata)

dataType:"json",

success:function(data){

if(typeof(data.error)=="undefined"){

$(".comment-reply").next().remove();//刪除已存在的所有回復(fù)div

//更新評論總數(shù)

$(".comment-num").children("span").html(data.num+"條評論");

//顯示新增評論

varnewli="";

if(cmdata.parent_id=="0"){

//發(fā)表的是一級評論時(shí)，添加到一級ul列表中

newli="licomment_id='"+data.id+"'divdivimgsrc='"+data.head_pic+"'alt=''/divdivdivspan"+data.nickname+"/spanspan"+data.create_time+"/span/divdivp"+data.content+"/p/divdivacomment_id='"+data.id+"'href='javascript:void(0);'回復(fù)/a/div/div/divul/ul/li

$(".comment-ul").prepend(newli);

}else{

//否則添加到對應(yīng)的孩子ul列表中

if('off'==replyswitch){//檢驗(yàn)出回復(fù)關(guān)閉鎖存在，即三級評論不再提供回復(fù)功能
