Getting the text from a drop-down box

问题

This gets the value of whatever is selected in my dropdown menu.

document.getElementById(\'newSkill\').value

I cannot however find out what property to go after for the text that\'s currently displayed by the drop down menu. I tried \"text\" then looked at W3Schools but that didn\'t have the answer, does anybody here know?

For those not sure, here\'s the HTML for a drop down box.

<select name=\"newSkill\" id=\"newSkill\">
    <option value=\"1\">A skill</option>
    <option value=\"2\">Another skill</option>
    <option value=\"3\">Yet another skill</option>
</select>

回答1:

Based on your example HTML code, here's one way to get the displayed text of the currently selected option:

var skillsSelect = document.getElementById("newSkill");
var selectedText = skillsSelect.options[skillsSelect.selectedIndex].text;

回答2:

Simply You can use Jquery instead of Javascript

$("#yourdropdownid option:selected").text();

Try This.

回答3:

This should return the text value of the selected value

var vSkill = document.getElementById('newSkill');

var vSkillText = vSkill.options[vSkill.selectedIndex].innerHTML;

alert(vSkillText);

Attaches a change event to the select that gets the text for each selected option and writes them in the div.

You can use jQuery it very face and successful and easy to use

<select name="sweets" multiple="multiple">
  <option>Chocolate</option>
  <option>Candy</option>
  <option>Taffy</option>
  <option selected="selected">Caramel</option>
  <option>Fudge</option>
  <option>Cookie</option>
</select>
<div></div>


$("select").change(function () {
  var str = "";

  $("select option:selected").each(function() {
    str += $( this ).text() + " ";
  });

  $( "div" ).text( str );
}).change();

回答7:

function getValue(obj)
{  
   // it will return the selected text
   // obj variable will contain the object of check box
   var text = obj.options[obj.selectedIndex].innerHTML ; 

}

HTML Snippet

 <asp:DropDownList ID="ddl" runat="server" CssClass="ComboXXX" 
  onchange="getValue(this)">
</asp:DropDownList>
