在 getJSON returns undefined 中使用每个函数
Using the each function within getJSON returns undefined
我正在使用 jQuery 的 getJSON 方法来检索和解析一个简单的 JSON 文件,但是当我将值输出到我的页面时,它显示为 undefined
$.getJSON( 'js/example.json', function ( data ) {
var output = '';
$.each( data.exercises, function ( index, exercise ) {
output += '<li>' + exercise.work.weight + ' x ' + exercise.work.reps + '</li>';
});
$( '#example' ).html( output );
});
example.json
{
"exercises" : [
{
"name" : "Squats",
"work" : [
{
"weight" : 135,
"reps" : 5
},
{
"weight" : 225,
"reps" : 5
},
{
"weight" : 315,
"reps" : 5
}
]
},
{
"name" : "Bench",
"work" : [
{
"weight" : 135,
"reps" : 5
},
{
"weight" : 225,
"reps" : 5
},
{
"weight" : 315,
"reps" : 5
}
]
},
{
"name" : "Rows",
"work" : [
{
"weight" : 135,
"reps" : 5
},
{
"weight" : 225,
"reps" : 5
},
{
"weight" : 315,
"reps" : 5
}
]
}
]
}
我认为错误可能出在我的每个函数中,但我还没有能够识别它。有什么想法吗?
这个:
output += '<li>' + exercise.work.weight + ' x ' + exercise.work.reps + '</li>';
假设您的 JSON 看起来像:
"exercises" : [
{
"name" : "Squats",
"work" :
{
"weight" : 135,
"reps" : 5
}
},
实际上 work
在每种情况下都是一个数组。
你想要这样的东西:
$.each( data.exercises, function ( index, exercise ) {
$.each( exercise.work, function( index, workout ) {
output += '<li>' + workout.weight + ' x ' + workout.reps + '</li>';
});
});
你的练习作品是一个数组,需要另一个循环
$.each( data.exercises, function ( index, exercise ) {
$.each(exercise.work, function (index, work) {
console.log(work);
});
});
