My HTML code looks like below:
<select id = "demo2">
<option value = "---select---">---select---</option>
<option value = "1">Oranges</option>
<option value = "2">Apples</option>
<option value = "3">Pears</option>
<option value = "4">Kiwis</option>
<option value = "5">Bananas</option>
<option value = "6">Banansasas</option>
<option value = "7">Grapes</option>
</select>
How do I open the option list of the select
tag on onfocus()
events?
Select lists are created using a combination of the HTML <select> and <option> tags. Select lists can be nested inside a <form> element or they can stand alone. They can also be associated with a form via the form attribute of the <select> tag.
HTML <select> Tag. The <select> tag in HTML is used to create a drop-down list. The <select> tag contains <option> tag to display the available option of drop-down list. Note: The <select> tag is used in a form to receive user responses.
To change the selected option of an HTML select element with JavaScript, we can set the value property of the select element. to add the select element. document. getElementById("sel").
$(document).ready(function(){
$('select').focus(function(){
$(this).attr("size",$(this).attr("expandto"));
var x = "select[tabindex='" + (parseInt($(this).attr('tabindex'),10) + 1) + "']";
$(x).fadeTo(50,0);
});
$('select').blur(function(){
$(this).attr("size",1);
var x = "select[tabindex='" + (parseInt($(this).attr('tabindex'),10) + 1) + "']";
$(x).fadeTo('fast',1.0);
});
});
