$( "#select_id" ).change( function (){ |
2 |
var checkText=$( "#select_id" ).find( "option:selected" ).text(); |
3 |
var checkValue=$( "#select_id" ).val(); |
4 |
var checkIndex=$( "#select_id " ).get(0).selectedIndex; |
5 |
var maxIndex=$( "#select_id option:last" ).attr( "index" ); |
6 |
$( "#select_id " ).get(0).selectedIndex=1; |
7 |
$( "#select_id " ).val(4); |
8 |
$( "#select_id option[text=‘jQuery‘]" ).attr( "selected" , true ); |
获取select 选中的 text :
1 |
$( "#ddlRegType" ).find( "option:selected" ).text(); |
获取select选中的 value:
获取select选中的索引:
1 |

设置select
jQuery添加/删除Select的Option项:
1 |
$( "#select_id" ).append( "<option value=‘Value‘>Text</option>" ); |
2 |
$( "#select_id" ).prepend( "<option value=‘0‘>请选择</option>" ); |
3 |
$( "#select_id option:last" ).remove(); |
4 |
$( "#select_id option[index=‘0‘]" ).remove(); |
5 |
$( "#select_id option[value=‘3‘]" ).remove(); |
6 |
$( "#select_id option[text=‘4‘]" ).remove(); |
设置select 选中的索引:
2 |
$( "#nowamagic" ).get(0).selectedIndex=index; |
设置select 选中的value:
1 |
$( "#nowamagic" ).attr( "value" , "Normal" ); |
2 |
$( "#nowamagic" ).val( "Normal" ); |
3 |
$( "#nowamagic" ).get(0).value = value; |
设置select 选中的text:
1 |
var count=$( "#nowamagicoption" ).length; |
2 |
for ( var i=0;i<count;i++) |
3 |
{ if ($( "#nowamagic" ).get(0).options[i].text == text) |
5 |
$( "#nowamagic" ).get(0).options[i].selected = true ; |
清空 select:
