Danmmu Player动态连接到数据库示例：

插入该插的css、js文件。

<div id="danmup"></div>

配置参数：

<script>
$("#danmup").DanmuPlayer({
islogin:<?PHP   echo($islogin); ?>,//自建属性
poster:"<?PHP if($obj->ImageURL==""){?>images/noImg.jpg<?PHP }else{?>user/images/<?PHP   echo($obj->ImageURL); ?><?PHP } ?>",//自建属性
src:"user/video/abc.mp4",//视频源
height: "480px", //区域的高度
width: "100%" ,//区域的宽度
urlToGetDanmu:"query.php",//从后端获取弹幕数据
urlToPostDanmu:"stone.php",//发送弹幕数据给后端保存入库
gd:<?PHP   echo($gid); ?>,//自建属性
ud:"<?PHP   echo($UserName); ?>",//自建属性
ndmid:ndmid,//自建属性
});
</script>

js中数据库参数处理部分：

//从后端获取弹幕
this.getDanmu = function () {
$.get(that.options.urlToGetDanmu,
{
GoodsId: that.options.gd,
ndmid:that.options.ndmid,
},
function (data, status) {
danmuFromSql = eval(data);
for (var i = 0; i < danmuFromSql.length; i++) {
try {
var danmuLs = eval('(' + danmuFromSql[i] + ')');

} catch (e) {
continue;
}
$(that.id + ' .danmu-div').danmu("addDanmu", danmuLs);
}
});
};
if (options.urlToGetDanmu)
this.getDanmu();
//发送弹幕
this.sendDanmu = function (e) {
var text = $(e.data.that.id + " .danmu-input").get(0).value;
if (text.length == 0) {
return;
}
if (text.length > 100){
alert("弹幕过长！");
return;
}
text = text.replace(/&/g, ">").replace(/</g, "<").replace(/>/g, ">").replace(/\"/g, """).replace(/\n/g, "<br>");
var color = e.data.that.danmuColor;
var position = $(e.data.that.id + " input[name=danmu_position]:checked").val();
var size = $(e.data.that.id + " input[name=danmu_size]:checked").val();
var time = $(e.data.that.id + " .danmu-div").data("nowTime") + 3;
var textObj = '{ "text":"'+e.data.that.options.ud+':' + text + '","color":"' + color + '","size":"' + size + '","position":"' + position + '","time":' + time + '}';
if(e.data.that.options.islogin==0){
$("#tishi").show();
}else{
if (e.data.that.options.urlToPostDanmu)
$.post(e.data.that.options.urlToPostDanmu,
{
danmu: textObj,
GoodsId: e.data.that.options.gd,
UserId:e.data.that.options.ud,
},
function(data){}
);
textObj = '{ "text":"'+e.data.that.options.ud+':' + text + '","color":"' + color + '","size":"' + size + '","position":"' + position + '","time":' + time + ',"isnew":""}';
var newObj = eval('(' + textObj + ')');
$(e.data.that.id + " .danmu-div").danmu("addDanmu", newObj);
$(e.data.that.id + " .danmu-input").get(0).value = '';
$(e.data.that).trigger("senddanmu");
}
