You can use the JavaScript Client Object Model. Assuming the window's _spPageContextInfoobject is set with the webServerRelativeUrl, pageListId, and pageItemIdproperties initialized:
您可以使用 JavaScript 客户端对象模型。假设窗口的_spPageContextInfo对象设置与webServerRelativeUrl，pageListId和pageItemId属性进行初始化：
var context = new SP.ClientContext(_spPageContextInfo.webServerRelativeUrl);
var list = context.get_web().get_lists().getById(_spPageContextInfo.pageListId);
var item = list.getItemById(_spPageContextInfo.pageItemId);
Then you can load the fields you need:
然后你可以加载你需要的字段：
context.load(item, "Title", "Location");
context.executeQueryAsync(Function.createDelegate(this, this.mySuccessFunction), Function.createDelegate(this, this.myErrorFunction));
itemwill now be populated with the fields you requested, and you can retrieve them like so:
item现在将填充您请求的字段，您可以像这样检索它们：
var itemTitle = item.get_item("Title");
var itemLocation = item.get_item("Location");
Note that you should use the display, not internal, names of the fields you want to load.
请注意，您应该使用要加载的字段的显示名称，而不是内部名称。

if _spPageContextInfo.pageItemId is undefined.
Use this function
function getUrlVars() {
var vars = [],
hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
//THEN DO THIS
var id = getUrlVars()["ID"];
//THEN DO YOUR MAGIC
var context = new SP.ClientContext(_spPageContextInfo.webServerRelativeUrl);
var list = context.get_web().get_lists().getById(_spPageContextInfo.pageListId);
var item = list.getItemById(id);
