<div>
前缀：<input id="txtBegin" type="text" value="" /> 后缀：<input id="txtEnd" type="text" value="" />
<br />
位数：<input id="numCount" type="number" value="5" />
</div>

<div style="margin:10px 0;">
<label><input type="radio" name="a1" onclick="fnNum();" checked /> 连续数字</label>
<label><input type="radio" name="a1" onclick="fnPwd();" /> 随机字符</label>
</div>

<div id="divNum">
范围：<input id="numBegin" type="number" value="0" /> ~ <input id="numEnd" type="number" value="100" />
<br />
过滤字符：<input id="txtLimit" type="text" value="" /> 多个使用,号分割
</div>

<div id="divPwd" style="display:none;">
