Now there is a id=test drop-down box, how to get the selected value?
Using JavaScript native methods and jquery methods, respectively
<select id= "test" name= "" >
<option value= "1" >text1</option>
<option value= "2" >text2</option>
</select>
Code
One: JavaScript native method
1: Get the Select object: Var myselect=document.getelementbyid ("Test");
2: Get the index of the selected item: Var index=myselect.selectedindex; //SelectedIndex represents the index of the item you selected
3: Get the selected options Value:myselect.options[index].value;
4: Get the selected options Text:myselect.options[index].text;
Two: JQuery method (provided that the jquery library has been loaded)
1:var options=$ ("#test option:selected"); Gets the selected item
2:alert (Options.val ()); Get the value of the selected item
3:alert (Options.text ()); Get the text of the selected item
just think and do it
JavaScript gets the value selected in the Select drop-down box and the index
