我想从JSP页面中的表单中读取一些输入,其中每个输入都具有相同的名称。见JSFiddle
如何从servlet中读取这些输入?
我尝试了String[] description = request.getParameterValues("description");
,但它无法正常工作..
有没有办法循环并读取这些值?
counter = 0;
var dataList = $('.products');
var jsonOptions = [{
"product": "11111",
"description": "description 1"
}, {
"product": "22222",
"description": "description 2"
}, {
"product": "33333",
"description": "description 3"
}];
jsonOptions.forEach(function(item) {
var option = '<option value="' + item.product + '">' + item.description + '</option>';
dataList.append(option);
});
$(function() {
$('body').on('input', '.product,.products', function() {
var i = this.value;
var description = "";
var productsInBox = 0;
jsonOptions.forEach(function(a) {
if (a.product == i) {
description = a.description;
productsInBox = a.productsInBox;
}
});
$(this).closest('.form-group').find('.description').val(description);
});
});
$('#form1').on('click', '.addButtonDED', function() {
var $template = $('.form-group:last').clone(true, true).find('input').val('').end().
find('.addButtonDED').removeClass('addButtonDED').addClass('removeButtonDED').end()
.find('i').removeClass('fa-plus').addClass('fa-minus').end();
$template.insertAfter('.form-group:last');
})
// Remove button click handler
.on('click', '.removeButtonDED', function() {
var $row = $(this).closest('.form-group');
$row.remove();
});

将名称更改为描述应该有效
<input type="text" class="form-control" name="description" />
或
String[] description = request.getParameterValues("description[]");
我更喜欢第一个,因为它不那么令人困惑。

在&lt; input&gt;中使用“description”作为名称,或使用request.getParameterValues("description[]")
,但在两边使用相同的名称。

这会奏效。
String[] description = request.getParameterValues("description[]");
