我的下拉列表如下:
<select id="HowYouKnow" >
<option value="1">FRIEND</option>
<option value="2">GOOGLE</option>
<option value="3">AGENT</option></select>
In the above dropdown i know the text of the dropdown. How can set the value of the dropdown in document.ready with the text using jquery?
This is a method that works based on the text of the option, not the index. Just tested.
var theText = "GOOGLE";
$("#HowYouKnow option:contains(" + theText + ")").attr('selected', 'selected');
或者，如果有类似的值(感谢shanabus):
$("#HowYouKnow option").each(function() {
if($(this).text() == theText) {
$(this).attr('selected', 'selected');
}
});
