jQuery.post(url, [data], [callback], [type])
url,[data],[callback],[type]String,Map,Function,StringV1.0url:發(fā)送請(qǐng)求地址。
data：待發(fā)送 Key/value 參數(shù)。
callback：發(fā)送成功時(shí)回調(diào)函數(shù)。
type：返回內(nèi)容格式，xml, html, script, json, text, _default。
套用格式：
$.post("test.php", function(data){
alert("Data Loaded: " + data);
});
$.get("comment/getComments?parentId="+parentId+"topicId="+topicId,function(data){
var appendButton ="";
var append = "";
if(data!=""){
var arr = data.split("$");
var allTr="";
for(var i = 0;iarr.length;i++){
var arr2 = arr[i].split(',');
var name = arr2[3];
var content = arr2[0];
var time= "/Date("+arr2[1]+")/";
time = DateFormat(time);
var id = arr2[2];
var table = "table>tr>td>"+content+"/td>/tr>tr>td>"+time+"/td>/tr>/table>";
appendButton = appendButton+table+"button type = 'button' id = 'toAddCommentId' onclick = 'replaceFrom("+parentId+",\""+name+"\""+")'>回復(fù)/button>";
}
appendButton = appendButton+"button type = 'button' onclick = 'replaceFrom("+parentId+","+"\""+userName+"\""+")'>我也說(shuō)一句/button>";
}
appendButton = appendButton+"div id = 'commentButton' >/div>div id = 'textareaId'>/div>";
if(data==""){
appendButton = appendButton+"textarea id='textareaId"+parentId+"' rows='2' cols='77' validate='required' validate-message='不能為空！' name = 'content' >@"+userName+"...."+"...."+parentId+":/textarea>button type = 'button' id = 'commentContentId' onclick = 'submit("+topicId+","+parentId+","+"\""+userName+"\""+")'>發(fā)表/button>";
}
$("#addCommentId"+parentId).html(appendButton);
});
后臺(tái)：
@RequestMapping(value = "/saveAndGetComments", params = {"topicId","parentId"}, method = RequestMethod.POST)
@ResponseBody
public String saveAndGetComments(long topicId,Comment comment,long parentId) throws UnsupportedEncodingException{
comment.setParentId(parentId);
commentService.save(comment,topicId);
ListComment> comments=commentService.listByCommentId(parentId);
return append(comments);
}
private String append(ListComment> comments) {
StringBuffer sb=new StringBuffer();
for(int i=0;icomments.size();i++){
Comment comment = comments.get(i);
sb.append(comment.getContent());
sb.append(",");
sb.append(comment.getCreateTime().getTime());
sb.append(",");
sb.append(comment.getId());
sb.append(",");
sb.append(comment.getUser().getName());
if(i!=comments.size()-1){
sb.append("$");
}
}
return sb.toString();
}
注意，用springmvc3的注解@responseBody來(lái)傳遞參數(shù)。
經(jīng)常用到的js函數(shù)：
上面由于使用json來(lái)傳遞的數(shù)據(jù)，而js解析json傳過(guò)來(lái)的日期時(shí)，不是我們想要的格式，這時(shí)需要對(duì)日期進(jìn)行操作：
首先傳過(guò)去的日期將它設(shè)為time傳過(guò)去 date.getTime()
然后再在js中操作：
var date= "/Date("+time+")/";
date = DateFormat(date);
/**
* 處理時(shí)間
* @param value
* @returns {String}
*/
function DateFormat(value) {
var date = new Date(parseInt(value.replace("/Date(", "").replace(")/", ""), 10));
var month = date.getMonth() + 1 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
var currentDate = date.getDate() 10 ? "0" + date.getDate() : date.getDate();
var Hours = date.getHours() 10 ? "0" + date.getHours() : date.getHours();
var Minutes = date.getMinutes() 10 ? "0" + date.getMinutes() : date.getMinutes();
var Seconds = date.getSeconds() 10 ? "0" + date.getSeconds() : date.getSeconds();
return date.getFullYear() + "/" + month + "/" + currentDate + " " + Hours + ":" + Minutes + ":" + Seconds;
}
