如何才能取到下面这个值
var value1 = $('div.m_con.m_jk div:visible div.m_progress.progress1 .num').text();
为什么这样出来的话会有1001000   2个值 ，如何才能只取到100这个值 ？

<div class="m_con m_jk">
<div id="tab1">
<div class="m_jk_c m_tab_c">
<div style="display: block">
<table>
<tr>
<td class="wd1"><span class="m_ico2_1"></span></td>
<td class="td1"></td>
