No data, when passing array trough an Ajax POST
提问by Mars
I'm trying to pass an array trough an Ajax POST request using jQuery. I can't seem to get it done. Here is my code:
我正在尝试使用 jQuery 通过 Ajax POST 请求传递数组。我似乎无法完成它。这是我的代码：
var settings = [];
$('.settingp input').each(function(){
settings[$(this).attr('id')] = $(this).val();
});
$.post("editSettings.php", { 'settings': settings });
The request happens, but there is no data in it. Any idea what am I doing wrong?
请求发生，但其中没有数据。知道我做错了什么吗？

the problem was
问题是
$(this).attr('id') => retuns a string, not a number
settings[$(this).attr('id')] = $(this).val();
changed it to and now it works
将其更改为现在可以使用了
settings[settings.length] = [$(this).attr('id'), $(this).val()];

What about this?
那这个呢？
var settings = {};
$('.settingp input').each(function(){
settings[$(this).attr('id')] = $(this).val();
});
$.post("editSettings.php", settings);
I think the issue is with our settings is initialized. Then when posting it, you don't have to call it "settings", since you have set all of the names of the post values already.
我认为问题在于我们的设置已初始化。然后在发布它时，您不必将其称为“设置”，因为您已经设置了所有发布值的名称。
