[英]How to loop through a JavaScript object with a condition and then output the data?
我做了两辆车:
var manana = {name: "manana", price: "$8,000", slots: "4"};
var walton = {name: "walton", price: "$12,000", slots: "7"};
对按钮点击做出反应,我想检查一个条件,看看哪辆车的价格等于 8,000 美元,槽位等于 4。如果是,它会在表格中输出它。
您需要在按钮上连接一个事件。 然后循环浏览您的车辆并测试状况。 就像是:
var manana = {name: "manana", price: "$8,000", slots: "4"};
var walton = {name: "walton", price: "$12,000", slots: "7"};
var vehicles = [manana, walton];
function eval() {
for (var i = 0; i < vehicles.length; i++) {
var vehicle = vehicles[i];
if (vehicle.price == '$8,000' && vehicle.slots == '4')
alert('found ' + vehicle.name);
}
}

这是我的答案,您可以重用具有不同价格和插槽条件或其他数组的函数:
var myArray = [{name: "manana", price: "$8,000", slots: "4"}, {name: "walton", price: "$12,000", slots: "7"}];
function retrieveNameUsingPriceAndSlots(pArray, pPrice, pSlots) {
for(var i = 0; i < pArray.length; i++) { //Loop through the array
var item = pArray[i];
if(item.price === pPrice && item.slots === pSlots) {
//If the item meets our condition, returns the name, and the code after this line wont be executed.
return item.name;
}
}
return false;
}
console.log(retrieveNameUsingPriceAndSlots(myArray, "$8,000", "4")); //manana
