我有以下对象,如果名称与变量匹配,我想要实现的是获取主题的索引。
例如:我在视图中循环,并且如果我的任务(something1
)变量与name元素匹配,则返回对象的索引。
通过给定的示例,我应该将结果设为0,
var views = [
{
name: "something1",
type: something1,
columns: something1
},
{
name: "something2",
type: something2,
columns: something2
},
{
name: "something3",
type: something3,
columns: something3
}
];
var task = 'something1';
$.each(views, function(index, value) {
if (value.name = task) {
alert(index);
}
});
最佳答案
您实际上不需要jQuery:
参见:http://jsfiddle.net/enNya/2/
var views = [
{
name: "something1",
type: "something1",
columns: "something1"
},
{
name: "something2",
type: "something2",
columns: "something2"
}
];
var task = 'something2';
// Set a var and maintain scope
var i;
// Loop each element of the array
for (i = 0; i < views.length; i++) {
// If the X = Y the stop looping
if (views[i].name == task) {
break;
}
}
// Check if it was not found
i = i == views.length ? false : i;
// Log the result
console.log(i);
