javascript SWITCH语句不触发

Question

我在 ASP.NET C# Web 应用程序的 javascript 中有一个 switch 语句。我正在用 FireBug 调试它，它出错了:它一到达 switch 就立即存在。

代码如下:

$(function() {

    $('#received_dateTextbox').mask("99/99/99");
    $('#report_dateTextBox').mask("99/99/99");
    $('#occurrence_dateTextBox').mask("99/99/99");

    //var checkValues='';

    $('table input:checkbox').click(function() {

        if ($(this).prop('checked')) {
            var checkText = $(this).next('a').text();
            var hrefValue = $(this).next('a').attr('href');
            var trimIndex = hrefValue.lastIndexOf('\\') + 1;
            var checkValue =  hrefValue.substr(trimIndex, hrefValue.indexOf("')",trimIndex)-trimIndex);

            //checkValues+=checkValue+";";

            switch(checkValue)
            {
                //preanalytical other
                case "21": 
                    var userInput = prompt("Other:", "Other:");
                    $(this).next('a').html('Other:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical other
                case "53": 
                    var userInput = prompt("Other:", "Other:");
                    $(this).next('a').html('Other:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //postanalytical other
                case "89": 
                    var userInput = prompt("Other:", "Other:");
                    $(this).next('a').html('Other:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //other other
                case "95": 
                    var userInput = prompt("Other:", "Other:");
                    $(this).next('a').html('Other:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical liquid handler instrument failure
                case "40":
                    var userInput = prompt("Liquid Handler#:", "Liquid Handler#:");
                    $(this).next('a').html('Liquid Handler#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical olympus instrument failure
                case "41":                   
                    var userInput = prompt("Olympus#:", "Olympus#:");
                    $(this).next('a').html('Olympus#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical lcms instrument failure
                case "42":
                    var userInput = prompt("LC-MS/MS#:", "LC-MS/MS#:");
                    $(this).next('a').html('LC-MS/MS#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical liquid handler delay prod
                case "49":
                    var userInput = prompt("Liquid Handler#:", "Liquid Handler#:");
                    $(this).next('a').html('Liquid Handler#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical olympus delay prod
                case "50":
                     var userInput = prompt("Olympus#:", "Olympus#:");
                    $(this).next('a').html('Olympus#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //analytical lcms delay prod
                case "51":
                    var userInput = prompt("LC-MS/MS#:", "LC-MS/MS#:");
                    $(this).next('a').html('LC-MS/MS#:' + '<font color="red">' + userInput + '</font>');
                    checkValues+=checkValue+":"+userInput;
                break;

                //wrong practice code
                case "63":
                    if (confirm("Do you want to check Report Sent to Wrong Location/Physician?"))
                    { var elNode = document.getElementById("TreeView1n82CheckBox");
                        $(elNode).prop("checked", true);
                     }
                    else
                    { var elNode = document.getElementById("TreeView1n81CheckBox");
                        $(elNode).prop("checked", false);
                    }

                break;  

                default: 
                    alert('no match');                
            }
        }
    });
    //document.getElementById('HiddenField1').value = checkValues;
});

调试器告诉我 checkValue 确实有一个值

我做错了什么？

Answer 1

checkValue 可以存储为数字，而不是所有“大小写”检查的字符串。

检查 case parseInt("95") : ... 是否有效。

此外，如果您向数字添加一个字符，然后检查您的案例是否开始工作，请检查:

switch(checkValue + 'A')

然后 case "53A": .... break;
