The first variable is something like:
第一个变量是这样的：

"count": 1,
"e": 1,
"k": null,

"q": "gabriel",
"start": 0,
"cards": [
{
"__guid__": "cdf8ee96538c3811a6a118c72365a9ec",
"company": false,

如何将 json 内容保存在另一个 javascript 变量中？

You would need a simple AJAX request to get the contents into a variable.
您需要一个简单的 AJAX 请求来将内容放入一个变量中。
var xhReq = new XMLHttpRequest();
xhReq.open("GET", yourUrl, false);
xhReq.send(null);
var jsonObject = JSON.parse(xhReq.responseText);
Please note that AJAX is bound by same-origin-policy, in case that URL is different this will fail.
请注意，AJAX 受same-origin-policy约束，如果 URL 不同，这将失败。

You can use like this

I think this might help you, using jQuery... :)
我认为这可能会帮助你，使用 jQuery ... :)
$.ajax({
beforeSend: function() { DO HERE WHATEVER }, //Show spinner
complete: function() { DO HERE WHATEVER }, //Hide spinner
type: 'POST',
url: Link,
dataType: 'JSON',
success: function(data){
var data = data;
OR IF YOU WANT SEPARATE THE VALUES...
var count = data.count;
var e = data.e;
var k = data.k;
...
}
});

This example considers the state of the request and will allow you to access the data from the JSON format using the dot operator.
此示例考虑了请求的状态，并允许您使用点运算符访问 JSON 格式的数据。
var request = new XMLHttpRequest();
request.open("GET", "mysite.com/json/public/search?q=variabile&k=&e=1", true);
request.setRequestHeader("Content-type", "application/json");
request.send();
request.onreadystatechange = function(){
if(request.ready == 4 && request.readyState == 200){
var response = request.responseText;
var obj = JSON.parse(response);
alert(obj.count); // should return the value of count (i.e Count = 1)
alert(obj.e); // should return the value of e (i.e. e = 1)
var count = obj.count; //store the result of count into your variable
var e = obj.e; //store the result of e into your variable
//...and so on
}
}
