Jquery在documentready上选择all作为默认值

下面是一个有效的答案: https://www.codeply.com/go/XxDu4DswTG

jQuery查询:

$('#basic').multiselect({
     //Add a default "select all" option instead of your custom one
     includeSelectAllOption: true,
     //Allow a number of displayed values in your menu
     numberDisplayed: 5
});

//Select all the values by default
$("#basic").multiselect('selectAll', false);
//Update the menu
$("#basic").multiselect('updateButtonText');

然后删除“all”选项的HTML:

<div class="container">
    <select id="basic" multiple="multiple">
        <option value="cheese">Cheese</option>
        <option value="tomatoes">Tomatoes</option>
        <option value="mozarella">Mozzarella</option>
        <option value="mushrooms">Mushrooms</option>
        <option value="pepperoni">Pepperoni</option>
        <option value="onions">Onions</option>
    </select>
</div>
