Question

每次点击按钮时，我都会尝试按钮显示警告。目前，它只在我第一次点击时触发，我必须刷新页面才能使其再次运行。因为这是一个Submit和New按钮，所以我需要它能够保留表单值，如果它重新加载就会丢失。警报用于向用户提供反馈。这是我的代码：

$('input[value="Submit and New"]').on('click', function(){
alert('The request form has been submitted successfully. To submit a new form for the same user, change the form values and click on either the "Submit" or "Submit and New" button');
});

Answer 1

使用文档设置单击，它应该可以正常工作

   $(document).on('click','input[value="Submit and New"]', function(){
    alert('The request form has been submitted successfully. To submit a new form for the same user, change the form values and click on either the "Submit" or "Submit and New" button');
    });

Answer 2

你可能在加载文档之前调用该函数，试试这个：

$(document).ready(function(){
    $('input[value="Submit and New"]').on('click', function(){
alert('The request form has been submitted successfully. To submit a new form for the same user, change the form values and click on either the "Submit" or "Submit and New" button');
    }
})
