Question

我有下面的jquery和一个返回数组的函数。我收到的myAnswers = ["Question 1=null", "Question 2=null", "Question 3=yes", "Question 4=yes", "Question 5=yes"]

数组

在下面的for循环中，我想处理每个数组元素的“=”之后的值

if question 1 = null ... do something
elseif question 1 = yes .. do another thing

如何分割这个以便我能够在=符号后测试值？

            $('#Continue').click(function() {
                var myAnswers = CheckRadioButtons(); 

                for (i = 0; i < myAnswers.length; i++) {       
                    var splitResult = myAnswers[1].split('=');
                    var expectedValue = splitResult[1];
                }
            });


            function CheckRadioButtons() {    
                var $rb = $('input:radio');
                var tempArray = new Array();
                var questionNo = 0;
                for (var i = 0; i < $rb.length; i += 2) {
                    ...some logic
                }
                return tempArray;
            }

Answer 1

您应该在i

中使用myAnswers[]

 for (i = 0; i < myAnswers.length; i++) {       
     var splitResult = myAnswers[i].split('=');
     var expectedValue = splitResult[1];

     // Note: Both null and yes will be a string.
     if(expectedValue=="null"){ // Do something}
     else if(expectedValue=="yes") { // Do something else }
 }

Answer 2

试试这个，value例如"Question 1=null"

value.split('=')[1] //Right hand side

拆分数组并使用等号后的值
