How to send parameters with jquery $.get()
提问by Dan Dinu
I'm trying to do a jquery GET and i want to send a parameter.
我正在尝试执行 jquery GET 并且我想发送一个参数。
here's my function:
这是我的功能：
$(function() {
var availableProductNames;
$.get("manageproducts.do?option=1", function(data){
availableProductNames = data.split(",");;
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
});
});
This doesn't seem to work; i get a null in my servlet when i use request.getParameter("option");
这似乎不起作用；当我使用时，我的 servlet 中得到一个空值request.getParameter("option")；
If i type the link into the browser http://www.myite.com/manageproducts.do?option=1it works perfectly.
如果我在浏览器中输入链接http://www.myite.com/manageproducts.do?option=1它可以完美运行。
I also tried:
我也试过：
$.get(
"manageproducts.do?",
{option: "1"},
function(data){}
which doesn't work either.
这也不起作用。
Can you please help me?
你能帮我么？
EDIT:
编辑：
also tried
也试过
$.ajax({
type: "GET",
url: "manageproducts.do",
data: "option=1",
success: function(msg){
availableProductNames = msg.split(",");
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
}
});
Still getting the same result.
仍然得到相同的结果。

If you say that it works with accessing directly manageproducts.do?option=1in the browser then it should work with:
如果您说它适用于直接manageproducts.do?option=1在浏览器中访问，那么它应该适用于：
$.get('manageproducts.do', { option: '1' }, function(data) {
...
});
as it would send the same GET request.
因为它会发送相同的 GET 请求。

Try this:
尝试这个：
$.ajax({
type: 'get',
url: 'manageproducts.do',
data: 'option=1',
success: function(data) {
availableProductNames = data.split(",");
alert(availableProductNames);
}
});
Also You have a few errors in your sample code, not sure if that was causing the error or it was just a typo upon entering the question.
此外，您的示例代码中存在一些错误，不确定这是导致错误的原因还是输入问题时的拼写错误。

I got this working : -
我得到了这个工作： -
$.get('api.php', 'client=mikescafe', function(data) {
...
});
It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.
它通过获取字符串 ?client=mikescafe 发送，然后在 api.php 中收集这个变量，并在你的 mysql 语句中使用它。

This is what worked for me:
这对我有用：
$.get({
method: 'GET',
url: 'api.php',
headers: {
'Content-Type': 'application/json',
},
// query parameters go under "data" as an Object
data: {
client: 'mikescafe'
}
});
will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe
将使一个 REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe
Good Luck.
祝你好运。
