Javascript to Select Multiple options

妖精的绣舞 提交于 2019-11-27 07:28:22
I have a form with a select box that allows multiple options. After a user saves these options, it stores them in a database table. I can then read this database table to get the options they chose one again. I need to be able to grab this data from the database, put it into an array, then have the options in that select box to be pre-selected when they go to "Edit" their options. Reading the data into an array is fine, and I know how to make a single option selected within a select box, however I'm not sure how to handle multiple options being selected in javascript. Can someone help me

Selectable <optgroup> in HTML <select> tag

左心房为你撑大大i 提交于 2019-11-27 07:10:32
Is there any way to make the option group selectable? <select> <optgroup value="0" label="Parent Tag"> <option value="1">Child Tag</option> <option value="2">Child Tag</option> </optgroup> </select> grifos I don't think you can but you can easily reproduce the visual style with css and thus only have options in your select, so everything is selectable. .optionGroup { font-weight: bold; font-style: italic; } .optionChild { padding-left: 15px; } <select multiple="multiple"> <option value="0" class="optionGroup">Parent Tag</option> <option value="1" class="optionChild">Child Tag</option> <option

jQuery get selected option value (not the text, but the attribute 'value')

随声附和 提交于 2019-11-27 06:13:10
Okay, I have this code: <select name="selector" id="selector"> <option value="1">Option 1</option> <option value="2">Option 2</option> </select> And I'd like to get the value of the option selected. Example: 'Option 2' is selected, and the value of it is '2'. The '2' is the value I need to get and not 'Option 2'. Use .val to get the value of the selected option.
