为什么javascript在php中将这些变量作为对象提供？
为什么javascript在php中将这些变量作为对象提供？
提问于 2019-05-22 05:38:49
我正在尝试将一些变量传递给PHP文件，以便运行SQL查询。但是，JavaScript将这些变量作为对象进行传递。为什么会发生这种情况？我如何才能改变这一点？

在发送之前使用JavaScript的JSON.stringify(your_variable)函数，在PHP端使用json_decode($_GET‘’data‘)
your_variable应该是一个对象，你不应该把它们包装成像代码一样。这样做：
data = {
var _memberID = $(row.children().get(1)).text(),
_MFirst = $(row.children().get(2)).text(),
_MLast = $(row.children().get(3)).text(),
_Street = $(row.children().get(4)).text(),
_number = $(row.children().get(5)).text(),
_postalCode = $(row.children().get(6)).text(),
_Mbirthdate = $(row.children().get(7)).text();
memberID.val(_memberID);
MFirst.val(_MFirst);
MLast.val(_MLast);
Street.val(_Street);
number.val(_number);
postalCode.val(_postalCode);
Mbirthdate.val(_Mbirthdate);
}然后通过ajax post将这个数据(字符串或报头设置为content- json_decode : application/json)传递给php，在php端应用我上面提到过的数据，你就有了一个数据数组用在sql查询中。
