Select the <select> element using JQuery selector. This selector is more specific and selecting the first element using option:nth-child(1). This will get access to the first element (Index starts with 1).
So you could use $("select"). prop("selectedIndex",0); for a quick way to select the first option on all dropdowns.
The :first selector selects the first element. Note: This selector can only select one single element. Use the :first-child selector to select more than one element (one for each parent). This is mostly used together with another selector to select the first element in a group (like in the example above).
Syntax of jQuery Select Option$(“selector option: selected”); The jQuery select option is used to display selected content in the option tag. text syntax is below: var variableValue = $(“selector option: selected”).
Try this out...
$('select option:first-child').attr("selected", "selected"); Another option would be this, but it will only work for one drop down list at a time as coded below:
var myDDL = $('myID'); myDDL[0].selectedIndex = 0; Take a look at this post on how to set based on value, its interesting but won't help you for this specific issue:
