jquery 表情輸入框利朵，可存數(shù)據(jù)庫

前兩天優(yōu)化博客的時候猎莲，想在留言評論版塊插入表情輸入功能，并且用戶能夠存入數(shù)據(jù)庫著洼，并且可以在前臺讀取展示姥份，于是研究了一下表情包年碘，解決方法如下：

• 下載表情包gif圖
  我下載的是新浪的表情包并且編譯如下：

• 表情路徑和表情內(nèi)容結(jié)合整理

 var faceList=[
            {'title':'微笑','url':'weixiao.gif'},

• 頁面結(jié)構(gòu)布完整

<div class="box">
    <div class="face-box">
            <textarea name="face" id="" cols="30" rows="10" placeholder="說點什么呢``" ></textarea>
            <div class="face-sina">
                <div class="face-logo">
                    <span>sina表情</span>
                </div>
                <div class="face-showbtn">
                    <span>展示</span>
                </div>
                <div class="face-sina-body">
                    <ul class="face-sina-items face-sina-items-show">
                    </ul>
                </div>
            </div>
    </div>
    <div class="face-show-box">
    </div>
</div>

• 給頁面表情列表賦值

var self = this;
var html = '';
 for(var i = 0;i<self.faceList.length;i++){
     var item = self.faceList[i];
     html +=' <li class="face-sina-item"  data-title="'+item.title+'"><img src="img/face/'+item.url+'" alt=""></li>'
 }
 $('.face-sina-items').html(html);

• 輸入框內(nèi)展示選擇內(nèi)容：通過點擊選擇事件獲取當前表情包的title 并賦值給到頁面的輸入框內(nèi)

  $('.face-sina-item').on('click',function(){
        var title = $(this).data("title");
        var textInner = $('textarea[name="face"]').val();
                textInner+="["+title+"]";
        $('textarea[name="face"]').val(textInner);
 });

• 數(shù)據(jù)解析轉(zhuǎn)換成表情包

$('.face-showbtn').on('click',function(){
        var cont =  $('textarea[name="face"]').val();
        var pat01 = /\[[\u4e00-\u9fa5]+\]/g;
        var pat02 = /\[[\u4e00-\u9fa5]+\]/;
        var content = cont.match(pat01);
        var str = cont;
        if(content){
            for(var i=0;i<content.length;i++){
                for(var j=0;j<self.faceList.length;j++){
                    if("["+self.faceList[j].title +"]" == content[i]){
                        var src = self.faceList[j].url;
                        break;
                    }
                }
                str = str.replace(pat02,'<img src="img/face/'+src+'"/>');
            }
        }
        $('.face-show-box').html(str).show();
    })
