[英]Changing Ajax data dynamically using a loop
The code below passes four parameters (names) to a PHP file and it works fine. 下面的代码将四个参数(名称)传递给PHP文件,并且工作正常。 Because in my application I have more than 4 names that change with time, I tried to use a loop with array and specify "n" as the number of names that I may have.
因为在我的应用程序中,我有4个以上的名称随时间变化,所以我尝试使用带有数组的循环,并指定“ n”作为我可能拥有的名称数量。 I could not find a way that made it work correctly.
我找不到使它正常工作的方法。 Can you show me how to change the working code below to include a loop where the number of names "n" is a variable.
您能告诉我如何更改下面的工作代码,以包括名称为“ n”个变量的循环。
var name1 = "a";
var name2 = "b";
var name3 = "c";
var name4 = "d";
$.ajax({
type: 'GET',
url: 'test12.php',
data: { par1: name1, par2: name2, par3: name3, par4: name4 },
});
Thnak you very much. 非常感谢您。
If all the names are globals, I would do: 如果所有名称都是全局名称,我会这样做:
var data = {}, n = 4;
for (i = 1; i <= n; i++)
data['par'+i] = window['name'+i];
$.ajax({
type: 'GET',
url: 'test12.php',
data: data // can be short-handed as "data" instead of "data: data"
});
If they are not globals, I would put the names in an array, and then loop through them this way instead: 如果它们不是全局变量,则将名称放入数组中,然后以这种方式遍历它们:
var data = {}, names = [name1, name2, name3, name4], n = names.length;
for (i = 1; i <= n; i++)
data['par'+i] = names[i-1];
$.ajax({
type: 'GET',
url: 'test12.php',
data
});
