DatePicker点击后重置表单输入框与选择框问题求助

Hey there! Let's break down why your form fields keep resetting when you click the DatePicker input, and fix this issue step by step.

最常见的原因：表单默认提交行为被触发 #

If your DatePicker input is wrapped inside a <form> tag, clicking it (or even elements from the DatePicker dropdown) might accidentally trigger the form's default submit action. When the form submits, the page refreshes, and all your input/select fields revert back to their initial load state—this is a super common gotcha!

解决方法：阻止表单默认提交 #

Add a listener to your form to stop the default submit behavior (you can still add custom submit logic later if you need it):

$('form').on('submit', function(e) {
  e.preventDefault();
  // Add your custom form submission code here if needed
});

其他可能的原因与修复方案 #

1. 事件冒泡引发的意外操作 #

The click event from the DatePicker might be bubbling up to a parent element that's triggering a form reset. Stop the event bubble directly on your DatePicker input:

$('.myClassDate').on('click', function(e) {
  e.stopPropagation();
});

2. 重复初始化或脚本冲突 #

Make sure your DatePicker initialization runs only once, after the DOM is fully loaded. Wrap it in $(document).ready() to avoid unexpected reinitializations:

$(document).ready(function() {
  $('.myClassDate').datepicker({ 
    format: "yyyy-mm-dd", 
    todayBtn: 'linked', 
    todayHighlight : true, 
    autoclose: true 
  });
});

Also, double-check if there are other scripts on the page that call form.reset() accidentally when clicking elements—search your codebase for any reset logic that might be firing unexpectedly.
