我正在尝试使用 Ajax 请求将表单发布到我的 testexe.php，但是，每当我在 Ajax 请求中添加数据类型网关时，我都会收到 Uncaught RangeError: Maximum call stack size超出错误信息。我在这里做错了什么吗？我能够成功获取按钮值，但不确定为什么gateway给我带来了问题。

最佳答案
给你一个解决方案
$.ajax({
url:"testexe.php",
type: "POST",
data: {
gateway: $("#gateway").val(),
option: $('input[type=radio]:checked').val()
},
dataType: "text",
success: function(result){
$('#div1').html(result)
}
});
错误是网关:网关。
我假设您想从输入文本框传递gateway值。
更改了代码网关:$("#gateway").val(),
希望这对您有帮助。
关于javascript - 当我提交表单时，我收到 Uncaught RangeError : Maximum call stack size exceeded，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45972396/
