Question

我目前正在开发一个程序来对一组并行数组进行排序。该程序假设使用myArray.sort()方法/函数对第一个数组进行排序。当程序打印出它们时，第二个数组值应与第一个数组排序保持一致。我认为我非常接近解决它但不能完全围绕它。sortArrays()函数是唯一需要工作的逻辑，其余的工作完美。任何帮助将不胜感激。

Javascript

var employeeName = [];
var employeeSal = [];
var tmpArrayName = [];
var tmpArraySal = [];
var arraySize = 0;

function getInfo() {
    arraySize = parseInt(prompt("How many employee records will you be adding today?"));
    while (isNaN(arraySize)) {
        arraySize = parseInt(prompt("Error: please enter a valid positive number for question (How many employee records will you be adding today?)"));
    }
    for (var l = 0; l < arraySize; l++) {
        employeeName[l] = prompt("Please enter the employee's last name and first name (ex: Wayne John)");
        employeeSal[l] = parseInt(prompt("Please enter the employee's yearly salary (ex: 62000)"));
        while (isNaN(employeeSal[l])) {
            employeeSal[l] = parseInt(prompt("Please enter the employee's yearly salary (ex: 62000)"));
        }
    }
    tmpArrayName = employeeName;
    tmpArraySal = employeeSal;
    employeeName.sort();
    sortArrays();
    printResult();
}

function sortArrays() {
    var index = 0;
    for (var i = 0; i < employeeName.length; i++) {
        index = employeeName.indexOf(tmpArrayName[i]);
        employeeSal[index] = tmpArraySal[i];
    }
}

function printResult() {
    for (var k = 0; k < employeeName.length; k++) {
        document.write('' + employeeName[k] + '&nbsp;&nbsp;' + employeeSal[k] + '<br/>');
    }
}

HTML

<body onload="getInfo()">
    <div id ="content">

    </div>
</body>

Answer 1

问题在于您没有复制数组，而是引用原始数组。要制作副本，请使用切片：

$('#zoomPicture').elevateZoom({
  scrollZoom : true,
  zoomWindowFadeIn: 250,
  zoomWindowFadeOut: 500,
  responsive: true,
  easing: true,
  easingDuration: 50,
  borderSize: 1,
  zoomWindowWidth: 400,
  zoomWindowHeight: 400,
});

$("#zoomPicture").bind("click", function(e) {
  console.log(e.pageX);
  console.log(e.pageY);
}); // -> undefined

应该是

tmpArrayName = employeeName;
tmpArraySal = employeeSal;

好的，这是最终解决方案。 @ caleb-an你的解决方案效果很好，但我通过使用for循环将tmpArrays值设置为原始数组来解决它。

//this code works fine but can not use
        //tmpArrayName = employeeName.slice(0);
        //tmpArraySal = employeeSal.slice(0);

       //this code does the same exact thing and works
       for (var e = 0; e < employeeName.length; e++)
       {
           tmpArrayName[e] = employeeName[e];
           tmpArraySal[e] = employeeSal[e];
       }

有没有办法像我想要的那样对两个并行数组进行排序
