3个jQuery脚本无法在HTML页面中一起使用

Question

我有一个包含3个jQuery脚本的HTML代码，但它们无法正常工作，可以有人帮我解决这个问题吗，请

我确实解决了这个问题，因为我没有jQuery的经验

以及如何解决此问题？

现在可以使用，但是一次只能使用一个下拉菜单

  (function() { var options = $("#DropDownList2").html(); $('#DropDownList2 :not([value^="Fac"])').remove(); $('input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList2").html(options); $('#DropDownList2 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList3").html(); $('#DropDownList3 :not([value^="Dip"])').remove(); $('input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList3").html(options); $('#DropDownList3 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList4").html(); $('#DropDownList4 :not([value^="Dr"])').remove(); $('input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList4").html(options); $('#DropDownList4 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })();

这里的问题是您的单选按钮更改事件彼此重叠，因此它们没有作用域，它们只能相互覆盖，请参见下面的更改，其中单选按钮输入现在包装在容器中，并且每个事件分别进行作用域。

值得注意的是，在下拉菜单和单选按钮集的每个部分周围使用范围，可以将代码重构为单个函数，从而可以处理所有事件。

 (function() { var options = $("#DropDownList2").html(); $('#DropDownList2 :not([value^="Fac"])').remove(); $('.group1 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList2").html(options); $('#DropDownList2 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList3").html(); $('#DropDownList3 :not([value^="Dip"])').remove(); $('.group2 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList3").html(options); $('#DropDownList3 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList4").html(); $('#DropDownList4 :not([value^="Dr"])').remove(); $('.group3 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList4").html(options); $('#DropDownList4 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })();
