我正在尝试编写一个函数，允许我根据下拉和文本框访问某个“管道”。这里的诀窍是下拉的某些选项要么需要ew（空重）或gvw（车辆总重量）或ft（英尺）或没有。我设置它的方式是下拉的值可以匹配var汽车中的字符串然后以某种方式它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权重。任何有关这方面的帮助将不胜感激！有人可以帮忙吗？
http://jsfiddle.net/wb9z2uuw/7/
**也许类似var exampleWeightClass = Automobiles [“2D”]。vehicleClass; ????怎么知道落入正确的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
}
}

答案 0 :(得分：1)
好的，我们去:)。在此处查看此操作：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 - 每个对象必须具有两个属性minWeight和maxWeight。如果minWeight和maxWeight属性对特定车辆不重要，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，变量被声明在函数之外，因此值保持不变，因为它们是函数第一次运行，这就是代码无法正常工作的原因一点都不。
原件：
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 - 只是为了帮助我理解我应该输入哪个值，我添加了一些动态隐藏和显示getWeight()函数中的文本框，如果你想要你可以删除它们< / p>
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
}
