People will naturally think of only one letter of the difference of the JSON bar ~JSON (JavaScript Object Notation) and Jsonp (JSON with Padding) have only a single letter difference, but they're not the same thing at all.JSON is a data interchange format, and Jsonp is an unofficial cross-domain data interaction protocol that relies on the ingenuity of developers

1. What is JSONP?JSONP (JSON with Padding) is an unofficial protocol that allows the server-side integration of script tags back to the client to achieve cross-domain access in the form of JavaScript callback (this is simply a JSONP implementation form).2. What is the use of JSONP?Due to the limitations of the same-origin policy, XMLHttpRequest only allows resources to request the current source (domain nam

Cross-Domain is a question that I often ask in everyday interviews, the word's frequency is not low in the front-end world, mainly because of security restrictions (homology policy, that is, JavaScript or cookies can only access the content under the same domain), because we will inevitably need to do cross-domain operations in our daily project development. So C

On the cross-domain, in the development of the project will inevitably encounter; before the author used EXTJS3.0 development project, in the development process encountered about cross-domain issues, but found on the internet most of the information is ExtJs4.0 or above version ofIn ExtJS, for example: Ext.Ajax.request, this is the way we use data requests, as i

-Generally the cross-domain exists only on the browser that has this problem. -If you encounter cross-domain issues+ 1. Accept data forwarding via your own server (the following methods are not secure)+ 2. In the sender's request header, add: Access-control-allow-origin: * (side server support)+ 3. Send data via JSONP

Ajax Cross-domain operation has been a difficult problem, now the main solutions are: 1, JSONP (need to support on the server side) 2, IFrame (can only operate in the subdomain) 3, page agent (this a little omnipotent) 4, Access-control-allow-origin (new browser support, need to set header on the server side) Today, kid.

The example of this article describes the method of jquery+thinkphp fetching data across domains. Share to everyone for your reference, specific as follows: Today do a remote crawl data function, remember jquery can use AJAX remote crawl, but not cross-domain. Find a lot on the Internet. But I think it's a combination, so I now feel a little complicated with sim

Obtaining data from the same domain can be achieved by XMLHTTP components or IFRAME, and there are no permissions issues with Cross-domain access, so it is simpler. However, if you want to access data from different domains, because of browser security settings, XMLHTTP does not have access to the
