                </select>
            </div>
        </div>
    </div>

    <div class="col-sm-3">
        <div class="form-group">
            <div class="input-group">
                <span style="min-width:50px;" class="input-group-addon">Company</span>
                <select required id="company_id_of_page" name="company_id" class="form-control">
                    <option value="">Please Select a Company</option>
                    <option value=0>Data Before Company Divition</option>
                    <option value=2>HP-CA</option>
                    <option value=1>HP-NY</option>
                </select>
            </div>
        </div>
    </div>
</div>

用于处理事件的jQuery是这样的：

$(document).ready(function(e)
{
    $(document).on("keyup change", "#start_date_of_page #end_date_of_page #state_id_of_page #company_id_of_page", function()
    {
        alert("Working!!!!");
    });
}

但是当有任何变化时没有警报，因此jQuery事件无效。

谁能告诉我我做错了什么？

Answer 1

工作正常，您的代码中出现语法错误

缺少，在选择器中

而不是

 "#start_date_of_page #end_date_of_page `#state_id_of_page #company_id_of_page"

使用

"#start_date_of_page,#end_date_of_page,`#state_id_of_page,#company_id_of_page"

Answer 2

$(function(){
    $(document).on('change', 'input,select', function(event){
        console.log(event);
        console.log( $(this).val() );
        alert("Working!!!!");
    });
});

jQuery - 在多个字段上应用多个事件 - 不工作
