使用jquery选择单选按钮文本字段和下拉菜单

Posted 2021-02-26

Just so I remember the next time..

Radio button
js:
[$("input[@name='the_name']:checked").val()]
 
html:
<input type="radio" name="the_name" value="0" /> Milk
<input type="radio" name="the_name" value="1" /> Coffie
 
the_name is the name of several buttons, and it's the items value that is selected 
 
 
Same method on a textfield:
 
js:
[$('input[@name="newCatField"]').val()]
 
html:
<input type="text" id="newCatField" name="newCatField"/>
same same.
 
On a dropdown menu:
 
js:
$('#myid :selected').val()
 
html:
<select id="myid">
<option value="1">Nyhet</option>
<option value="2">Sport</option>
<option value="3">Utenriks</option>
</select>
