How to use the ajax parameter of jQuery skillfully to use JSON?
This issue of the content of the editor will bring you about jQuery ajax reference skillful use of JSON how to use the process, the article is rich in content and professional analysis and description for you, after reading this article, I hope you can get something.
The ajax call of jQuery is very convenient, and you like to use the data format of Json when passing parameters. For example:
The code is as follows:
Function AddComment (content) {
Var threadId = $("# span_thread_id") .html ()
Var groupId = $("# span_group_id") .html ()
Var groupType = $("# span_group_type") .html ()
Var title = $("# thread_title") .html ()
Var content = content.replace (/\ x22andggamo'"')
$.ajax ({
Url:'/ WebService/GroupService.asmx/AddThreadComment'
Data:'{threadId:' + threadId +', groupId:' + groupId +', groupType:' + groupType +', title: "'+ title +'", content: "'+ content +'"}', type: 'post'
DataType: 'json'
ContentType: 'application/json;charset=utf-8'
Cache: false
Success: function (data) {
/ / judge whether it is successful according to the returned value data.d
}
Error: function (xhr) {
/ / if an exception occurs in the middle, check xhr.responseText
}
});
}
The most troublesome and error-prone thing is to concatenate Json strings, add quotation marks to the values of character parameters, and give special treatment to', /, etc. for the text fields entered by the user.
As an unexpected opportunity, my boss recommended me a new method. Look at the following code:
The code is as follows:
Function AddComment (content) {
Var comment = {}
Comment.threadId = $("# span_thread_id") .html ()
Comment.groupId = $("# span_group_id") .html ()
Comment.groupType = $("# span_group_type") .html ()
Comment.title = $("# thread_title") .html ()
Comment.content = content
$.ajax ({
Url:'/ WebService/GroupService.asmx/AddThreadComment'
Data: $.toJSON (comment)
Type: 'post'
DataType: 'json'
ContentType: 'application/json;charset=utf-8'
Cache: false
Success: function (data) {
/ / processed according to the returned value data.d
}
Error: function (xhr) {
/ / an exception occurred in the middle. Check xhr.responseText for more information.
}
});
}
Just use $.toJSON (object) directly.
