我有一个json数组
var data = [ { "id": "1", "label": 1, "value": "11.00" },
{ "id": "2", "label": 2, "value": "21.00" },
{ "id": "3", "label": 3, "value": "31.00" },
{ "id": "4", "label": 4, "value": "40.00" },
{ "id": "5", "label": 5, "value": "50.00" },
{ "id": "6", "label": 6, "value": "60.00" },
{ "id": "9", "label": 9, "value": "90.00" },
{ "id": "8", "label": 8, "value": "80.00" },
{ "id": "7", "label": 7, "value": "70.00" }
];

<form action="" method="POST">

Product1: <select name="product1" id="product1"><option value="1">Product 1</option><option value="2">Product 2</option></select>

我想自动填充产品的价格。我很抱歉我不了解jquery和javascript。 尝试了这个但没有奏效
$( "#product1" ).change(function(){
source: data,
minLength: 1,
select: function( event, ui ) {
$('#price1').val( ui.item.value );
}
});
请帮助我如何填充product1的price1 id产品1和price2。
以下是#product1
的代码$('#product1').change(function() {
$('input[name="unit_price1"]').val(data[$(this).val()-1].value)
});
但是一旦我尝试循环,我的循环就不会出错了。
$(function() {
var data = <?php echo $projects; ?>;
var nbProducts = data.length;
for(var iProduct = 0; iProduct < nbProducts; iProduct++) {
$('#product'+iProduct).change(function() {
$('input[name="unit_price'+iProduct+'"]').val(data[$(this).val()-1].value)
});
}
});

var data = [ { "id": "1", "label": 1, "value": "11.00" },
{ "id": "2", "label": 2, "value": "21.00" },
{ "id": "3", "label": 3, "value": "31.00" },
{ "id": "4", "label": 4, "value": "40.00" },
{ "id": "5", "label": 5, "value": "50.00" },
{ "id": "6", "label": 6, "value": "60.00" },
{ "id": "9", "label": 9, "value": "90.00" },
{ "id": "8", "label": 8, "value": "80.00" },
{ "id": "7", "label": 7, "value": "70.00" }
];
for(var i=0; i<data.length; i++) {
$('#product1').append('<option value="' + data[i].value + '">' + data[i].label+ '</option>');
$('#product2').append('<option value="' + data[i].value + '">' + data[i].label+ '</option>');
}
$('#product1').change(function() {
$('input[name="price1"]').val($(this).val())
});
$('#product2').change(function() {
$('input[name="price2"]').val($(this).val())
});
也许你会接近这个决定。示例:http://jsfiddle.net/YvZ9v/

您可以使用以下代码绑定change事件:
$( "#product1" ).change(function() {
var nbProducts = data.length;
for(var iProduct = 0; iProduct < nbProducts; iProduct++) {
if(data[iProduct].id == this.value)
$('#price1').val( data[iProduct].value );
}
}
修改强> 为了遍历所有产品输入,你只需要迭代:
var nbProducts = data.length;
for(var iProduct = 1; iProduct <= nbProducts; iProduct++) {
$('#product'+iProduct).change(function() {
// Same code as above...
});
}
