JS表情替换代码,这里使用字符取代图片路径

需求:将一段字符串中出现的特定字符替换为指定的图片或其他 解决的方法:
<script>
var json = ‘[{"title":"微笑","src":14},{"title":"撇嘴","src":2},{"title":"色","src":3},{"title":"发呆","src":4},{"title":"得意","src":5},{"title":"流泪","src":200},{"title":"害羞","src":6},{"title":"闭嘴","src":7},{"title":"睡","src":8},{"title":"大哭","src":9},{"title":"尴尬","src":10},{"title":"发怒","src":11},{"title":"调皮","src":12},{"title":"呲牙","src":13},{"title":"吃惊","src":1},{"title":"难过","src":15},{"title":"酷","src":16},{"title":"冷汗","src":63},{"title":"抓狂","src":17},{"title":"吐","src":18},{"title":"偷笑","src":19},{"title":"可爱","src":20},{"title":"白眼","src":21},{"title":"傲慢","src":22},{"title":"饥饿","src":23},{"title":"困","src":24},{"title":"惊恐","src":25},{"title":"流汗","src":26},{"title":"憨笑","src":27},{"title":"大兵","src":28},{"title":"奋斗","src":29},{"title":"咒骂","src":201},{"title":"疑问","src":30},{"title":"嘘","src":31},{"title":"晕","src":32},{"title":"折磨","src":202},{"title":"衰","src":33},{"title":"骷髅","src":34},{"title":"敲打","src":35},{"title":"再见","src":36},{"title":"察汗","src":203},{"title":"抠鼻","src":64},{"title":"鼓掌","src":65},{"title":"糗大了","src":66},{"title":"坏笑","src":67},{"title":"左哼哼","src":68},{"title":"右哼哼","src":69},{"title":"哈欠","src":70},{"title":"歧视","src":71},{"title":"委屈","src":72},{"title":"快哭了","src":73},{"title":"阴险","src":74},{"title":"亲亲","src":75},{"title":"吓","src":76},{"title":"可怜","src":77},{"title":"菜刀","src":204},{"title":"西瓜","src":62},{"title":"啤酒","src":205},{"title":"篮球","src":206},{"title":"兵乓","src":207},{"title":"咖啡","src":8},{"title":"饭","src":49},{"title":"猪头","src":40},{"title":"玫瑰","src":50},{"title":"凋谢了","src":51},{"title":"示爱","src":208},{"title":"爱心","src":52},{"title":"心碎","src":53},{"title":"蛋糕","src":42},{"title":"闪电","src":43},{"title":"炸弹","src":44},{"title":"刀","src":45}]‘;
json = eval(‘(‘+ json +‘)‘);
var pattern1 = /\[[\u4e00-\u9fa5]+\]/g;
var pattern2 = /\[[\u4e00-\u9fa5]+\]/;
var contents = "[微笑]美女[色]你好[害羞]在吗?";
content = contents.match(pattern1);
str = contents;
for(i=0;i<content.length;i++){
for(j=0;j<json.length;j++){
if("["+ json[j].title +"]" == content[i]){
src = http://www.mamicode.com/json[j].src;>
过程:

1、分析JSON字符串中各内容的涵义

2、利用正則表達式找出须要替换的内容

3、利用两次循环,并结合推断将相应内容替换
<script type="text/javascript"> $(function () { $(‘pre.prettyprint code‘).each(function () { var lines = $(this).text().split(‘\n‘).length; var $numbering = $(‘
    ‘).addClass(‘pre-numbering‘).hide(); $(this).addClass(‘has-numbering‘).parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($(‘
  • ‘).text(i)); }; $numbering.fadeIn(1700); }); }); </script>
