Pass array of data to jQuery function
提问by Ben Everard
Here's the story... I have a jQuery function that does something, this function is referenced very regularly. One of the input parameters is an array, this array data is hard coded and thus I want to pass the data like this: (this is how I would do it using PHP)
故事是这样的……我有一个 jQuery 函数可以做一些事情，这个函数经常被引用。输入参数之一是一个数组，这个数组数据是硬编码的，因此我想像这样传递数据：（这是我使用 PHP 的方式）
myFunction(Array("url"=>"abc.com","example"=>"hello_world"));
Instead of
代替
$arr=Array("url"=>"abc.com","example"=>"hello_world");
myFunction($arr);
So how do I achieve this with my jQuery function, I want this to be a one liner if possible.
那么我如何用我的 jQuery 函数实现这一点，如果可能的话，我希望它是一个单线。

Maybe my example was a bit misleading, take a look at the array indexes again. The array I am sending is an associative array.
也许我的例子有点误导，再看看数组索引。我发送的数组是一个关联数组。
In short I do not want any variables before my function, I want the array to be hardcoded directly in the function parameter as suggested in the first example I gave.
简而言之，我不希望在我的函数之前有任何变量，我希望按照我给出的第一个示例中的建议，直接在函数参数中对数组进行硬编码。

I reread your edited question, and your answer is in the javascript object, much like dictionaries or hashes in other languages:
我重读了你编辑过的问题，你的答案在 javascript 对象中，很像其他语言的字典或哈希：
{ first_key: '1', second_key: '2', third_key: '3' };
And for your callback, just pass it in as a literal declared on the spot:
对于您的回调，只需将其作为当场声明的文字传递：
myFunction({ first_key: '1', second_key: '2', third_key: '3'});

Here is example if this is what you mean:
这是示例，如果这是您的意思：
var arr = [ "one", "two", "three", "four", "five" ];
jQuery.each(arr, function() {
$("#" + this).text("Mine is " + this + ".");
return (this != "three"); // will stop running after "three"
});

Look into JSON formatting for your array...
查看数组的 JSON 格式...
somefunction({'key1':'value', 'key2':'value'});

I'm not entirely sure what you're asking here, but I'll give answering it a shot. If you're referencing this array in more than one place then it's probably best to define it as a constant first:
我不完全确定你在这里问的是什么，但我会试一试。如果您在多个地方引用此数组，那么最好先将其定义为常量：
ARRAY = ['a', 'b', 'c']
myFunction(ARRAY);
myFunction2(ARRAY);
If your only referencing this hard-coded array once, then pass it into the jQuery function as an array literal declared in the function call:
如果您只引用一次这个硬编码数组，则将它作为在函数调用中声明的数组文字传递到 jQuery 函数中：
myFunction(['a', 'b', 'c']);

JavaScript does not have associative arrays. You can probably get what you are asking for with a combination of regular arrays and objects:
JavaScript 没有关联数组。您可能可以通过常规数组和对象的组合获得所需的内容：
var foo = [
{
url: "abc.com",
example: "hello_world"
},
{
url: "example.net",
example: "example"
}
];
There is a data format called JSON that uses JavaScript syntax. Since you seem to be using PHP and PHP has builtin functions to generate JSON (find json_encode()in the PHP manual) it can be a very simple task: encode your PHP data structure as JSON and use it as is from JavaScript.
有一种称为 JSON 的数据格式，它使用 JavaScript 语法。由于您似乎在使用 PHP 并且 PHP 具有生成 JSON 的内置函数（在 PHP 手册中查找json_encode()），因此它可以是一项非常简单的任务：将您的 PHP 数据结构编码为 JSON 并按原样从 JavaScript 使用它。
