Set Selected Option Of Select Box
I want to set a option that was selected previously to be displayed on page load. I tried it with the following code: $('#gate').val('Gateway 2'); with
Solution 1:
This definitely should work. Here's a demo. Make sure you have placed your code into a $(document).ready:
$(function() {
$("#gate").val('gateway_2');
});
Solution 2:
$(document).ready(function() {
$("#gate option[value='Gateway 2']").prop('selected', true);
// you need to specify id of combo to set right combo, if more than one combo
});
Solution 3:
$('#gate').val('Gateway 2').prop('selected', true);
Solution 4:
$("#form-field").val("5").trigger("change");
Solution 5:
I have found using the jQuery .val() method to have a significant drawback.
<select id="gate"></select>
$("#gate").val("Gateway 2");
If this select box (or any other input object) is in a form and there is a reset button used in the form, when the reset button is clicked the set value will get cleared and not reset to the beginning value as you would expect.
This seems to work the best for me.
For Select boxes
<select id="gate"></select>
$("#gate option[value='Gateway 2']").attr("selected", true);
For text inputs
<input type="text" id="gate" />
$("#gate").attr("value", "your desired value")
For textarea inputs
<textarea id="gate"></textarea>
$("#gate").html("your desired value")
For checkbox boxes
<input type="checkbox" id="gate" />
$("#gate option[value='Gateway 2']").attr("checked", true);
For radio buttons
<input type="radio" id="gate" value="this"/> or <input type="radio" id="gate" value="that"/>
$("#gate[value='this']").attr("checked", true);
