长度超出规定长度，显示省略号
设置class为displayPart，
设置自定义属，displayLength可显示长度（不包含...），双字节字符，长度 *2，
复制代码 代码如下:
<script type="text/javascript">
$.fn.extend({
displayPart:function () {
var displayLength = 100;
displayLength = this.attr("displayLength") || displayLength;
var text = this.text();
if (!text) return "";
var result = "";
var count = 0;
for (var i = 0; i < displayLength; i++) {
var _char = text.charAt(i);
if (count >= displayLength) break;
if (/[^x00-xff]/.test(_char)) count++; //双字节字符，//[u4e00-u9fa5]中文
result += _char;
count++;
}
if (result.length < text.length) {
result += "...";
}
this.text(result);
}
});
$(function () {
$(".displayPart").displayPart();
});
</script>
