Question

我有一个通过xsl样式表显示的调查。我有一个部分检查用户是否选择＆＃34;两者都没有＆＃34;对于多个选项，如果是，则显示另一个问题。

这是JQuery：

function block3Check(){
    var neither23 = $('input[name=response23]:checked', '#editForm').val();
    var neither24 = $('input[name=response24]:checked', '#editForm').val();
    var neither25 = $('input[name=response25]:checked', '#editForm').val();
    var neither26 = $('input[name=response26]:checked', '#editForm').val();

    if(neither23 && neither24 && neither25 && neither26 == 'Neither')
    {

        $('#question-27').slideDown(500);
        $('#after-link').hide();
    }
}

我没有收到有关此代码的错误或警告，但我认为该错误存在于我的IF语句或我的XSL代码中。如果所有选项都没有被选中，则新问题应该向下滑动，但是如果选择了4个中的3个，则当前会这样做。

XSL：

任何帮助都将不胜感激。

Answer 1

您的if语句始终为false。你应该检查所有变量的'Neither'值，如下所示：

 if(neither23 == 'Neither' && neither24 == 'Neither' && neither25 == 'Neither' && neither26 == 'Neither') {
     $('#question-27').slideDown(500);
     $('#after-link').hide();
 }

Answer 2

if(neither23 && neither24 && neither25 && neither26 == 'Neither') 如果你想检查所有等于Neither，那那就错了。

您可以使用Array.prototype.every()（使用polyfill支持旧浏览器）：

if([neither23,neither24,neither25,neither26].every(function(elm){ return elm === 'Neither';})) {
  $('#question-27').slideDown(500);
  $('#after-link').hide();
}
