我正在尝试编写一个函数，该函数允许我基于下拉列表和文本框访问某个“管道”。这里的技巧是，下拉列表中的某些选项要么需要 ew(空重)，要么需要 gvw(车辆总重)，要么需要 ft(英尺)，或者不需要。我设置的方式是，下拉列表的值可以与 var cars 中的字符串匹配，然后以某种方式需要知道如何根据用户在正确的相应文本框中输入的内容来访问正确的重量。任何对此的帮助将不胜感激!有人可以帮忙吗？

** 也许类似于 var exampleWeightClass = Automobiles["2D"].vehicleClass; ????它如何知道属于正确的vehicleClass并知道它来自哪个文本框？
function getWeight(vehicle) {
if(vehicle == '2D' || vehicle == '3D' || vehicle == '4D' || vehicle == '5D' || vehicle == 'CV' || vehicle == 'UT' || vehicle == 'SW' || vehicle == 'TL1' || vehicle == 'TL2' || vehicle == 'PK' || vehicle == 'VN1' || vehicle == 'VN3' || vehicle == 'CA2' ||vehicle == 'PC' || vehicle == 'MH' ) {
return $('#ew').val(); //WEIGHT BASED ON EW
}
else if(vehicle == 'TK1' || vehicle == 'TK2' || vehicle == 'TK3' || vehicle == 'TK4' || vehicle == 'TK5' || vehicle == 'VN2' ) {
return $('#gvw').val(); //WEIGHT BASED ON GVW
}
else if(vehicle == 'HS1' || vehicle == 'HS2' || vehicle == 'TV1' || vehicle == 'TV2' ) {
return $('#ft').val(); //WEIGHT BASED ON FT
}
else {
return 0; //CA1, HS3, PT1, PT2, MC1, MC2, MP
}
}

好的，我们开始吧:)。在这里查看它的实际情况:http://jsfiddle.net/wb9z2uuw/11/
我在代码中发现了一些问题。首先 - 在您的数据集中 - 每个对象都必须具有两个属性 minWeight 和 maxWeight。如果 minWeight 和 maxWeight 属性对于特定车辆并不重要，则将它们分别设置为 0 和 Number.MAX_VALUE。这可确保检索管道值的函数正常工作。例如:
"PT1": [{
vehicleClass: "none",
minWeight: 0,
maxWeight: Number.MAX_VALUE,
pipe: [6.25, 6.25, 6.25, 12.50, 12.50, 12.50, 25.00, 25.00, 25.00, 25.00, 25.00, 25.00, 31.25, 31.25, 31.25, 1, 36.60, 25.00, 2, 2, 0, 76]
}],
第二 - 在 eventHandler() 函数中，变量是在函数外部声明的，因此这些值保留为函数第一次运行时的样子，这就是代码不存在的原因根本不工作。
原文:
var weight = getWeight(vehiclebody.options[vehiclebody.selectedIndex].value);
var vehiclebody = document.getElementById("vehiclebody");
var eventHandler = function () {
if (weight !== "" && vehiclebody.options[vehiclebody.selectedIndex].value != "") {
for (var i in Automobiles) {
if (i === vehiclebody.options[vehiclebody.selectedIndex].value) {
for (var a = 0; a < Automobiles[i].length; a++) {
if (weight >= Automobiles[i][a].minWeight && weight < Automobiles[i][a].maxWeight) {
alert(Automobiles[i][a].pipe);
break;
}
}
break;
}
}
}
};
新:
var eventHandler = function () {
var weight = getWeight();
var vehiclebody = $("#vehiclebody").val();
if (weight !== "" && vehiclebody != "") {
for (var i in Automobiles) {
if (i === vehiclebody) {
for (var a = 0; a < Automobiles[i].length; a++) {
if (weight >= Automobiles[i][a].minWeight && weight < Automobiles[i][a].maxWeight) {
alert(Automobiles[i][a].pipe);
break;
}
}
break;
}
}
}
};
另外 - 只是为了帮助我稍微了解一下我应该输入哪个值，我在 getWeight() 函数中添加了一些动态隐藏和显示文本框的功能，您可以删除如果你想要这些
if (vehicle == '2D' || vehicle == '3D' || vehicle == '4D' || vehicle == '5D' || vehicle == 'CV' || vehicle == 'UT' || vehicle == 'SW' || vehicle == 'TL1' || vehicle == 'TL2' || vehicle == 'PK' || vehicle == 'VN1' || vehicle == 'VN3' || vehicle == 'CA2' || vehicle == 'PC' || vehicle == 'MH') {
$("#gvw, label[for='gvw'], #ft, label[for='ft']").val("").hide();
$("#ew, label[for='ew']").show();
weight = $('#ew').val(); //WEIGHT BASED ON EW
}
