Boostrap Modal内部的表单不会重置 [英] Form inside Boostrap Modal does not reset

问题描述

我正在使用以下点击事件来重置表单.

I am using below click event to reset Form.

'click .resetBulkAssignForm' : function(events, template){
    console.log('Reset', $(".bulkAssignForm")[0]);
    $(".bulkAssignForm")[0].reset();
    $(".bulkAssignForm").find("select").val("");
    $('#firmName').select2('data', null);
},

推荐答案

更改Select2的基础<select>或<input>的值后，您必须触发change事件，以便此更改将由Select2代码并正确渲染:

After changing value of Select2's underlying <select> or <input> you have to trigger change event so this change will be handled by Select2 code and rendered appropriately:

$(".bulkAssignForm").find("select").val("").trigger("change");
