如何根据所有表单输入复选框列表名称创建动态变量名称？这就是我到目前为止所拥有的
var nameArray = [];
$.each($("#store-filter input").serializeArray(), function(i, field) {
nameArray[field.name] = field.value;
});
alert(nameArray[0]);
for (i = 0; nameArray.length > i; i++)
{
//alert(nameArray[i]);
var nameArray[i] = nameArray[i].value;
var nameArray[i]+'_checked_values' = $(\'input[name="nameArray[i]+[]"]:checked\').map(function() {
return this.value;
}).get();
}
alert(make); //variable name from name="make[]"
示例HTML
<form id="store-filter" action:"javascript:void(0);">
<span id="store">
<input id="store_0" value="2" name="store[]" type="checkbox"> <label for="store_0">Store 1</label>
<input id="store_1" value="3" name="store[]" type="checkbox"> <label for="store_1">Store 2</label>
<input id="store_2" value="3" name="store[]" type="checkbox"> <label for="store_2">Store 3</label>
</span>
<span id="make">
<input id="make_0" value="2" name="make[]" type="checkbox"> <label for="make_0">make
1</label>
<input id="make_1" value="3" name="make[]" type="checkbox"> <label for="make_1">make
2</label>
<input id="make_2" value="4" name="make[]" type="checkbox"> <label for="make_2">make
3</label>
</span>
<span id="time">
<input id="time_0" value="2" name="time[]" type="checkbox"> <label for="time_0">time 1</label>
<input id="time_1" value="3" name="time[]" type="checkbox"> <label for="time_1">time 2</label>
<input id="time_2" value="4" name="time[]" type="checkbox"> <label for="time_2">time 3</label>
</span>
</form>
所以稍后在我的代码中我可以创建一个url字符串?make=1,2,3&store=40,5,6&time=1,2,3,4等
$ _GET参数取自输入复选框名称动态

我建议使用以下方法，显然我只需点击按钮，就应该将其添加到您选择的事件/互动中：
function makeQueryString() {
function keyValues(idPref) {
// using the pass-in 'id' as a key:
var key = idPref,
// searching within the element identified with that 'id' for
// other elements whose 'id' *starts* with that string:
values = $('#' + idPref + ' input[id^="' + idPref + '"]').map(function() {
// iterating over those found elements and, if the value is *not* the
// defaultValue (value on page-load), *or* the checked state is not the
// default state (checked/unchecked as on page-load):
if (this.value !== this.defaultValue || this.checked !== this.defaultChecked) {
// we return the value:
return this.value;
}
// get() converts to a JavaScript Array, join() concatenates Array elements
// to form a string:
}).get().join(',');
// if there is a key, and there are associated values, we return a 'key=value,value2'
// string, otherwise we return an empty string:
return key && values.length ? key + '=' + values : '';
}
// we return the value obtained after iterating over the form's span elements
// that have an [id] attribute:
return $('form span[id]').map(function(){
// obtaining the 'key=value1,value2' strings from the called-function:
return keyValues(this.id);
// converting those returned elements into an Array, and joining with & characters:
}).get().join('&');
}
$('#test').click(function(e) {
e.preventDefault();
console.log(makeQueryString());
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="test">test</button>
<form id="store-filter" action: "javascript:void(0);">
<span id="store">
<input id="store_0" value="2" name="store[]" type="checkbox"> <label for="store_0">Store 1</label>
<input id="store_1" value="3" name="store[]" type="checkbox"> <label for="store_1">Store 2</label>
<input id="store_2" value="3" name="store[]" type="checkbox"> <label for="store_2">Store 3</label>
</span>
<span id="make">
<input id="make_0" value="2" name="make[]" type="checkbox"> <label for="make_0">make
1</label>
<input id="make_1" value="3" name="make[]" type="checkbox"> <label for="make_1">make
2</label>
<input id="make_2" value="4" name="make[]" type="checkbox"> <label for="make_2">make
3</label>
</span>
<span id="time">
<input id="time_0" value="2" name="time[]" type="checkbox"> <label for="time_0">time 1</label>
<input id="time_1" value="3" name="time[]" type="checkbox"> <label for="time_1">time 2</label>
<input id="time_2" value="4" name="time[]" type="checkbox"> <label for="time_2">time 3</label>
</span>
</form>

你使用Javascript，你不需要声明数组的大小，通过添加/删除对象/数组中的任何内容没有问题。
你应该创建一个变量make然后获取值。最后，你将能够取回它。
var make;
$.each($("#store-filter input").serializeArray(), function(i, field) {
make[i] = field.name;
});
稍后在您的代码中，您将使用数组make。
make[0];
编辑：
以下是我为您做的一个例子：http://jsfiddle.net/kjkzm8qm/
注意：您的 $。each（$（＆＃34; #store-filter input＆＃34;）。serializeArray（）... 没用，您应该通过添加选择所有输入一个AND类，你应该通过在末尾添加一个来结束输入标记。
HTML
<input name="test" class="inputs" />
JAVASCRIPT
$.each($(".inputs"), function(){ });

更新大卫的回答。
如果你想删除&然后在下面添加这个代码
对于此检查，键值不为空
let keyValue = keyValues(this.id);
if (keyValue != ''){
return keyValue;
}
