jquery - 如何为 jQuery 制作 switch case？

Question

我有这个 if-else 语句，它给了我奇怪的响应...每当我首先选择“输出”时，之后选择的任何其他内容都不会出现... 仅供引用，我正在使用多项选择，因此我可以选择并显示任意数量的内容。

 $('#outputText').hide();
    $('#armCB').hide();
    $('#outputCB').hide();
    $('#zoneText').hide();
    $('#counterText').hide();
    $('#flagText').hide();
    $('#sensorText').hide();

('#select-choice-1').change(function(){
        if ($('#output').is(':selected')){
            $('#outputText').show();
        }
        else if ($('#arm').is(':selected')){
            $('#armCB').show();
        }
        else if ($('#zone').is(':selected')){
            $('#zoneText').show();
        }
        else if ($('#counter').is(':selected')){
            $('#counterText').show();
        }
        else if ($('#flag').is(':selected')){
            $('#flagText').show();
        }
        else if ($('#sensor').is(':selected')){
            $('#sensorText').show();
        }
        else{
            $('#outputText').hide();
            $('#armCB').hide();
            $('#zoneText').hide();
            $('#counterText').hide();
            $('#flagText').hide();
            $('#sensorText').hide();

        }

我的 if-else 语句有错误吗？或者我必须在这里使用 Switch case 语句？如果是的话我该怎么办？

Answer 1

这只是标准的 javascript : http://www.w3schools.com/js/js_switch.asp

switch(n) {
 case 1:
  //execute code block 1
  break;
 case 2:
  //execute code block 2
  break;
 default:
 // code to be executed if n is different from case 1 and 2
}                           

其中开关变量将是所选标签的名称
