问题描述
HTML:
code>属性,当它第一次遇到选择。HTML:
<select id="dropdown"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select>jQuery:
$("#dropdown").prepend("<option value='' selected='selected'></option>");When I run this in FireFox or Chrome, the drop down has the newly inserted blank option selected. When I run it in IE8, it still has Volvo selected. Any ideas?
解决方案Change it to this, and it'll work:
$("#theSelectId").prepend("<option value=''></option>").val('');It seems that IE only evaluates the selected attribute when it first encounters the select.
