Question

我正在使用select选项值来处理部分代码，并希望显示更改时的特定div并隐藏其他内容。但是我无法使其正常工作，这是我的代码。

我不明白为什么div没有出现在与第二个示例相反的第一个示例中。

我的目标是在选项卡1中具有选项卡并添加选择选项，在选项卡2中添加div，当我在选项卡1中选择选项时，它会自动在选项卡2中显示结果。我希望我很清楚。

jQuery(function($) {

  $(".segment-select").Segment();

});


$(document).ready(function() {
  $(document).on("click", ".ui-segment span", function() {
    var value = $(this).attr('value');
    $(".box").hide();
    $(".box." + value).show();
  });
  $(".ui-segment span:first").click();
});

(function($) {
  $.fn.extend({
    Segment: function() {
      $(this).each(function() {
        var self = $(this);
        var onchange = self.attr('onchange');
        var wrapper = $("<div>", {
          class: "ui-segment"
        });
        $(this).find("option").each(function() {
          var option = $("<span>", {
            class: 'option',
            onclick: onchange,
            text: $(this).text(),
            value: $(this).val()
          });
          if ($(this).is(":selected")) {
            option.addClass("active");
          }
          wrapper.append(option);
        });
        wrapper.find("span.option").click(function() {
          wrapper.find("span.option").removeClass("active");
          $(this).addClass("active");
          self.val($(this).attr('value'));
        });
        $(this).after(wrapper);
        $(this).hide();
      });
    }

  });

})(jQuery);

如果检查DOM，则会发现选择框已转换为DIV-> SPAN结构并将其显示为选项卡。因此，此处的普通选择框更改事件将不会触发。您需要在跨度上绑定click事件并读取value属性，然后应用逻辑来显示和隐藏div。

请参见下面的工作片段

jQuery(function ($){

        $(".segment-select").Segment();
          
      });

    
$(document).ready(function(){
    $(document).on("click",".ui-segment span",function(){
        var value= $(this).attr('value');
        $(".box").hide();
        $(".box." + value).show();
    });
   $(".ui-segment span:first").click();
});



(function( $ ){
    $.fn.extend({
        Segment: function ( ) {
			$(this).each(function (){
				var self = $(this);
				var onchange = self.attr('onchange');
				var wrapper = $("<div>",{class: "ui-segment"});
				$(this).find("option").each(function (){
					var option = $("<span>",{class: 'option',onclick:onchange,text: $(this).text(),value: $(this).val()});
					if ($(this).is(":selected")){
						option.addClass("active");
					}
					wrapper.append(option);
				});
				wrapper.find("span.option").click(function (){
					wrapper.find("span.option").removeClass("active");
					$(this).addClass("active");
					self.val($(this).attr('value'));
				});
				$(this).after(wrapper);
				$(this).hide();
			});
        }

    });
        
})(jQuery);

在选项上，选择显示div并隐藏其他人
