自从换了一个新主题后,我遇到了一些问题,包括 DataTables 强>。 jQuery 只被调用一次并且被放置在正确的位置,所以基本上一切都是正确的。
我收到这样的消息
TypeError: $(...).DataTable is not a function
或
TypeError: $ is undefined
在 DataTables 下,我有一个带有 load() 和类似问题的不同 JS。我可以在放置它时修复它:
jQuery(document).ready(function($){
在此之前:
$("#tmp").load("tmp.htm")
我在一些论坛上看到,占位符 $ 可能存在问题。无论如何,上面的部分解决了我的问题。但回到数据表。我认为这是同样的问题,但我无法理解这个问题。
我的表格开始于:
$(document).ready(function() {
var tabelle = $('#mytable').DataTable(
但是之前有了这个..
jQuery(document).ready(function($){
我只得到错误。有人可以帮帮我吗?

最佳答案
我遇到了同样的问题,下面的代码解决了这个问题
jQuery(文档).ready(函数($){
关于javascript - "DataTable is not a function"$-issue/-conflict(jQuery 和新主题),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/27545812/
