jquery设置页面内IFrame 里RadioButton的Text值

  <asp:RadioButton ID="rbStepY1" runat="server" GroupName="a" Text="步骤1" onclick="rbStepN2.checked=true;" />
  <asp:RadioButton ID="rbStepY2" runat="server" GroupName="a" Text="步骤2" onclick="rbStepN1.checked=true;" />

解析到html为

 <input id="rbStepY1" type="radio" name="a" value="rbStepY1" onclick="rbStepN2.checked=true;" /><label for="rbStepY1">步骤1</label> 

<input id="rbStepY2" type="radio" name="a" value="rbStepY2" onclick="rbStepN1.checked=true;" /><label for="rbStepY2">步骤2</label>

var t= $("#ifmProperty").contents().find("#rbStepY1").next().text();//获取值 t="步骤1"

$("#ifmProperty").contents().find("#rbStepY1").next().text("abc");//设置rbStepY1 的值为“abc”
