[英]Passing prompt data from javascript to php using ajax
First of all i know there are multiple topics about this on stackoverflow, i read most of them but i still cant figure out why the following is not working. 首先,我知道有很多关于stackoverflow的主题,我阅读了其中的大部分内容,但仍然无法弄清以下内容为何无效。
So i have a form like this: 所以我有这样的形式:
echo "<td> <form action=\"admin.php\" method=\"GET\" onsubmit=\" modifyPassword();\">
this is the modifyPassword function: 这是ModifyPassword函数:
function modifyPassword(){
var newpw=prompt("Enter a new password");
if(newpw !== null){
$.ajax({
type: "GET",
url: "admin.php",
data: newpw,
success: function(data)
{
console.log(data);
}
});
}}
And when the form is actually submitted i want to get the value from what is typed in like this: 当实际提交表单时,我想从这样输入的内容中获取值:
echo $_GET['data'];
This is all in the same file. 全部都在同一个文件中。 The output of $_GET['data'] does not show anything. $ _GET ['data']的输出不显示任何内容。
Can someone tell me what i am doing wrong? 有人可以告诉我我在做什么错吗?
//edit, more code: I am using multiple forms, so here is the code that handles the form: //编辑,更多代码:我正在使用多种形式,因此这里是处理该形式的代码:
}elseif (isset($_GET['Modify'])){
echo $_GET['data'];
Form itself: 形式本身:
echo "<td> <form action=\"admin.php\" method=\"GET\" onsubmit=\" modifyPassword();\">
<input type='hidden' name='counter' value=\"$count\"/>
<input type=\"submit\" value=\"Modify\" name=\"Modify\"/>
Function that is provided: 提供的功能:
<script type="text/javascript">
function modifyPassword(){
var newpw=prompt("Enter a new password");
if(newpw !== null){
$.ajax({
type: "GET",
url: "admin.php",
data: {data: newpw}, // passing a key/value pair
success: function(data)
{
console.log(data);
}
});
}}
</script>
data: newpw,
should be data: {data: newpw},
This will result in $_GET['data']
being populated. data: newpw,
应为data: {data: newpw},
这将导致填充$_GET['data']
。 In this case 'data' becomes the key, while 'newpw' is the value. 在这种情况下,“数据”成为关键,而“ newpw”成为关键。
function modifyPassword(){
var newpw=prompt("Enter a new password");
if(newpw !== null){
$.ajax({
type: "GET",
url: "admin.php",
data: {data: newpw}, // passing a key/value pair
success: function(data)
{
console.log(data);
}
});
}}
I will argue that you should not use so many variables with the same name - just to make things less confusing during bug hunting. 我将争辩说,您不应使用太多同名的变量-只是为了减少在寻找错误时造成的混乱。
