1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。<div id="Demo" style="text-align:center;"><div class="Main"> <div class="Input_Box"> <textarea class="Input_text"></textarea> <div class="faceDiv"> </div> <div class="Input_Foot"> <a class="imgBtn" href="javascript:void(0);"></a><a class="postBtn">确定</a> </div> </div></div></div>
4、书写css代码。<style>.Main { width: 500px; height: 500px; margin: 0 auto; margin-top: 100px; }.Input_Box { width: 495px; height: 160px; border: 1px solid #ccc; transition: border linear .2s, box-shadow linear .5s; -moz-transition: border linear .2s, -moz-box-shadow linear .5s; -webkit-transition: border linear .2s, -webkit-box-shadow linear .5s; -moz-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; background-color: #fff; overflow: hidden; position: absolute; -moz-box-shadow: 0 0 5px #ccc; -webkit-box-shadow: 0 0 5px #ccc; box-shadow: 0 0 5px #ccc; }.Input_Box>textarea { width: 485px; height: 111px; padding: 5px; outline: none; border: 0px solid #fff; resize: none; font: 13px "微软雅黑", Arial, Helvetica, sans-serif; -moz-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; }.Input_Foot { width: 100%; height: 35px; border-top: 1px solid #ccc; background-color: #fff; -moz-border-radius: 0 0 5px 5px; -webkit-border-radius: 0 0 5px 5px; border-radius: 0 0 5px 5px; position: absolute; }.imgBtn { float: left; margin-top: 8px; margin-left: 10px; background-image: url(imgs.png); background-repeat: no-repeat; background-position: 0 -13px; height: 18px; width: 20px; cursor: pointer }.imgBtn:active { margin-top: 9px; }.imgBtn:hover { background-position: 0 -31px }.postBtn { float: right; font: 13px "微软雅黑", Arial, Helvetica, sans-serif; color: #808080; padding: 9px 20px 7px 20px; border-left: 1px solid #ccc; cursor: pointer; -moz-border-radius: 0 0 5px 0; -webkit-border-radius: 0 0 5px 0; border-radius: 0 0 5px 0; }.postBtn:hover { color: #333; background-color: #efefef; }.postBtn:active { padding: 10px 20px 6px 20px; }.faceDiv { width: 500px; height: 120px; border-top: 1px solid #ccc; position: absolute; background-color: #fff; -moz-border-radius: 5px 5px 0 0; -webkit-border-radius: 5px 5px 0 0; border-radius: 5px 5px 0 0; }.faceDiv>img { border: 1px solid #ccc; float: left; margin-left: -1px; margin-top: -1px; position: relative; width: 24px; height: 24px; padding: 3px 3px 3px 3px; cursor: pointer; }.faceDiv>img:hover { background-color: #efefef; }.faceDiv>img:active { padding: 4px 3px 2px 3px; }</style>
5、<script src="js/jquery.min.js"></script><script>$(document).ready(function(e) { ImgIputHandler.Init();});var ImgIputHandler={ facePath:[ {faceName:"微笑",facePath:"0.gif"}, {faceName:"撇嘴",facePath:"1.gif"}, {faceName:"色",facePath:"2.gif"}, {faceName:"发呆",facePath:"3.gif"}, {faceName:"得意",facePath:"4.gif"}, {faceName:"流泪",facePath:"5.gif"}, {faceName:"害羞",facePath:"6.gif"}, {faceName:"闭嘴",facePath:"7.gif"}, {faceName:"大哭",facePath:"9.gif"}, {faceName:"尴尬",facePath:"10.gif"}, {faceName:"发怒",facePath:"11.gif"}, {faceName:"调皮",facePath:"12.gif"}, {faceName:"龇牙",facePath:"13.gif"}, {faceName:"惊讶",facePath:"14.gif"}, {faceName:"难过",facePath:"15.gif"}, {faceName:"酷",facePath:"16.gif"}, {faceName:"冷汗",facePath:"17.gif"}, {faceName:"抓狂",facePath:"18.gif"}, {faceName:"吐",facePath:"19.gif"}, {faceName:"偷笑",facePath:"20.gif"}, {faceName:"可爱",facePath:"21.gif"}, {faceName:"白眼",facePath:"22.gif"}, {faceName:"傲慢",facePath:"23.gif"}, {faceName:"饥饿",facePath:"24.gif"}, {faceName:"困",facePath:"25.gif"}, {faceName:"惊恐",facePath:"26.gif"}, {faceName:"流汗",facePath:"27.gif"}, {faceName:"憨笑",facePath:"28.gif"}, {faceName:"大兵",facePath:"29.gif"}, {faceName:"奋斗",facePath:"30.gif"}, {faceName:"咒骂",facePath:"31.gif"}, {faceName:"疑问",facePath:"32.gif"}, {faceName:"嘘",facePath:"33.gif"}, {faceName:"晕",facePath:"34.gif"}, {faceName:"折磨",facePath:"35.gif"}, {faceName:"衰",facePath:"36.gif"}, {faceName:"骷髅",facePath:"37.gif"}, {faceName:"敲打",facePath:"38.gif"}, {faceName:"再见",facePath:"39.gif"}, {faceName:"擦汗",facePath:"40.gif"}, {faceName:"抠鼻",facePath:"41.gif"}, {faceName:"鼓掌",facePath:"42.gif"}, {faceName:"糗大了",facePath:"43.gif"}, {faceName:"坏笑",facePath:"44.gif"}, {faceName:"左哼哼",facePath:"45.gif"}, {faceName:"右哼哼",facePath:"46.gif"}, {faceName:"哈欠",facePath:"47.gif"}, {faceName:"鄙视",facePath:"48.gif"}, {faceName:"委屈",facePath:"49.gif"}, {faceName:"快哭了",facePath:"50.gif"}, {faceName:"阴险",facePath:"51.gif"}, {faceName:"亲亲",facePath:"52.gif"}, {faceName:"吓",facePath:"53.gif"}, {faceName:"可怜",facePath:"54.gif"}, {faceName:"菜刀",facePath:"55.gif"}, {faceName:"西瓜",facePath:"56.gif"}, {faceName:"啤酒",facePath:"57.gif"}, {faceName:"篮球",facePath:"58.gif"}, {faceName:"乒乓",facePath:"59.gif"}, {faceName:"拥抱",facePath:"78.gif"}, {faceName:"握手",facePath:"81.gif"}, ] , Init:function(){ var isShowImg=false; $(".Input_text").focusout(function(){ $(this).parent().css("border-color", "#cccccc"); $(this).parent().css("box-shadow", "none"); $(this).parent().css("-moz-box-shadow", "none"); $(this).parent().css("-webkit-box-shadow", "none"); }); $(".Input_text").focus(function(){ $(this).parent().css("border-color", "rgba(19,105,172,.75)"); $(this).parent().css("box-shadow", "0 0 3px rgba(19,105,192,.5)"); $(this).parent().css("-moz-box-shadow", "0 0 3px rgba(241,39,232,.5)"); $(this).parent().css("-webkit-box-shadow", "0 0 3px rgba(19,105,252,3)"); }); $(".imgBtn").click(function(){ if(isShowImg==false){ isShowImg=true; $(this).parent().prev().animate({marginTop:"-125px"},300); if($(".faceDiv").children().length==0){ for(var i=0;i<ImgIputHandler.facePath.length;i++){ $(".faceDiv").append("<img title=\""+ImgIputHandler.facePath[i].faceName+"\" src=\"face/"+ImgIputHandler.facePath[i].facePath+"\" />"); } $(".faceDiv>img").click(function(){ isShowImg=false; $(this).parent().animate({marginTop:"0px"},300); ImgIputHandler.insertAtCursor($(".Input_text")[0],"["+$(this).attr("title")+"]"); }); } }else{ isShowImg=false; $(this).parent().prev().animate({marginTop:"0px"},300); } }); $(".postBtn").click(function(){ alert($(".Input_text").val()); }); }, insertAtCursor:function(myField, myValue) { if (document.selection) { myField.focus(); sel = document.selection.createRange(); sel.text = myValue; sel.select(); } else if (myField.selectionStart || myField.selectionStart == "0") { var startPos = myField.selectionStart; var endPos = myField.selectionEnd; var restoreTop = myField.scrollTop; myField.value = myField.value.substring(0, startPos) + myValue + myField.value.substring(endPos, myField.value.length); if (restoreTop > 0) { myField.scrollTop = restoreTop; } myField.focus(); myField.selectionStart = startPos + myValue.length; myField.selectionEnd = startPos + myValue.length; } else { myField.value += myValue; myField.focus(); }}}</script>
6、代码整体结构。
7、查看效果。
