jQuery - selected attribute on options doesn't show in FireBug
问题 Why? when I select a option in a select field, the selected="selected" attribute still stays on the previous option. But visually you can see that the new option is active 回答1: Selecting an option from the dropdown doesn't modify the selected attribute in the DOM. But if you query the current value using $('#selectId').val() it would return the value of the currently selected option. 来源: https://stackoverflow.com/questions/4842159/jquery-selected-attribute-on-options-doesnt-show-in-firebug
