Handling Custom Data Types (dealing with custom data types)
JQuery's Ajax implements a set of standard data types, such as text, json, xml, and html.
Use the converters option in $.ajaxSetup () to add or modify data types using the $.ajax () conversion strategy.
The unchanged jQuery code itself contains a default converter for a list, which is a powerful example of how they can be used:
/ / List of data converters
/ / 1) key format is "source_type destination_type"
/ / (a single space in-between)
/ / 2) the catchall symbol "*" can be used for source_type
Converters: {
/ / Convert anything to text
"* text": window.String
/ / Text to html (true = no transformation)
"text html": true
/ / Evaluate text as a json expression
"text json": jQuery.parseJSON
/ / Parse text as xml
"text xml": jQuery.parseXML
}
When you specify a converters option globally in $.ajaxSetup (), or each time you call $.ajax (), this object will be mapped to the default converter, overriding those you specified and leaving everything else unchanged.
For example, the jQuery code uses $.ajaxSetup () to add a "text script" converter:
JQuery.ajaxSetup ({
Accepts: {
Script: "text/javascript, application/javascript"
}
Contents: {
Script: / javascript/
}
Converters: {
"text script": jQuery.globalEval
}
})
