Question

是否可以从我的网站本地运行脚本而不是将其连接到Jquery.com托管的库/查询？目前，它在线连接到另一个页面以执行查询，但是所有功能都在代码中，我需要它在本地运行，而不需要在线librbary或后台的任何库

由于

代码：

Answer 1

您可以从here下载脚本文件并将其存储在本地计算机上。然后在HTML页面中使用<script src="path/to/jquery.min.js" type="text/javascript></script>来获取jQuery。

Answer 2

您想要实现的目标很有可能，但您必须将jQuery选择器和方法更改为javascript版本的选择器和方法，如：

如果您有$('#selector')表示选择id，那么您可以做的是：

改变这个：

$('#selector')

到此：

document.getElementById('selector')

同样适用于以下方法：

.val()

到

.value

所以改变这个：

 $('#selector').val()

到此：

document.getElementById('selector').value;

您可以将jQuery的.text()更改为javascript的.innerHTML。

和当前$(document).ready(function() {....});必须更改为javascript的window.onload=function(){...};

Answer 3

在本地下载和使用jQuery，或者只使用普通的JS

在我做了一些更改之后，这是脚本的DEMO。它不起作用，因为HTML不包含所需的所有东西，如正则表达式

var calvalid;

function calvalidate_field (field_id) {
  var fld = document.getElementById(field_id);
  var value = fld.value;
  var tmp_reg_exp = fld.parentNode.getElementsByClassName("validator_exp")[0].innerHTML;
  reg_exp = new RegExp(tmp_reg_exp);
  if (!value.match(reg_exp) || (field_id == "form_repeat_password" && !check_password("form_new_user_password","form_repeat_password"))) {
    calvalid = false;
    return false;
  }
  return true;
}


var caldeadline = [
  [0,135,153,188,235,318],[0,124,141,170,206,288],[0,106,129,153,177,235], 
  [0,106,129,153,177,235],[0,106,129,153,177,235], [0,106,129,153,177,235],

window.onload=function() {
