From f7ed2aca562620f9424b1667170352e798e99ef3 Mon Sep 17 00:00:00 2001 From: jaubourg Date: Sat, 25 Dec 2010 18:54:37 +0100 Subject: [PATCH] Removed re-usability from jXHR object (no more open, send & onreadystatechange support). Streamlined the implementation and put it back into ajax.js (removed xhr.js in the process). Went back to a more simple & direct approach to options handling (keeping much room to further minification-related optimizations). Code is cleaner, smaller & faster. Removed & edited unit tests accordingly. All build files have had xhr.js removed. --- Makefile | 1 - Rakefile | 2 +- build.xml | 1 - src/ajax.js | 582 +++++++++++++++++++++++++++++++++++- src/transports/jsonp.js | 2 +- src/transports/script.js | 2 +- src/transports/xhr.js | 2 +- src/xhr.js | 728 ---------------------------------------------- test/index.html | 1 - test/unit/ajax.js | 164 +---------- 10 files changed, 581 insertions(+), 904 deletions(-) delete mode 100644 src/xhr.js diff --git a/Makefile b/Makefile index 935f69c..f69aa63 100644 --- a/Makefile +++ b/Makefile @@ -24,7 +24,6 @@ BASE_FILES = ${SRC_DIR}/core.js\ ${SRC_DIR}/manipulation.js\ ${SRC_DIR}/css.js\ ${SRC_DIR}/ajax.js\ - ${SRC_DIR}/xhr.js\ ${SRC_DIR}/transports/jsonp.js\ ${SRC_DIR}/transports/script.js\ ${SRC_DIR}/transports/xhr.js\ diff --git a/Rakefile b/Rakefile index 5ea143b..4d72a1c 100644 --- a/Rakefile +++ b/Rakefile @@ -9,7 +9,7 @@ test_dir = File.join( prefix, 'test' ) # setting DIST_DIR before calling rake dist_dir = ENV['DIST_DIR'] || File.join( prefix, 'dist' ) -base_files = %w{intro core support data queue attributes event selector traversing manipulation css ajax xhr transports/jsonp transports/script transports/xhr effects offset dimensions outro}.map { |js| File.join( src_dir, "#{js}.js" ) } +base_files = %w{intro core support data queue attributes event selector traversing manipulation css ajax transports/jsonp transports/script transports/xhr effects offset dimensions outro}.map { |js| File.join( src_dir, "#{js}.js" ) } # Sizzle, QUnit and jQuery files/dirs sizzle_dir = File.join( src_dir, "sizzle" ) diff --git a/build.xml b/build.xml index f6650f4..f2f805f 100644 --- a/build.xml +++ b/build.xml @@ -63,7 +63,6 @@ - diff --git a/src/ajax.js b/src/ajax.js index 5c655b5..9f8e238 100644 --- a/src/ajax.js +++ b/src/ajax.js @@ -1,12 +1,20 @@ (function( jQuery ) { -var rscript = /)<[^<]*)*<\/script>/gi, - rselectTextarea = /^(?:select|textarea)/i, - rinput = /^(?:color|date|datetime|email|hidden|month|number|password|range|search|tel|text|time|url|week)$/i, +var r20 = /%20/g, rbracket = /\[\]$/, + rhash = /#.*$/, + rheaders = /^(.*?):\s*(.*?)\r?$/mg, // IE leaves an \r character at EOL + rinput = /^(?:color|date|datetime|email|hidden|month|number|password|range|search|tel|text|time|url|week)$/i, + rnoContent = /^(?:GET|HEAD)$/, rquery = /\?/, - r20 = /%20/g, + rscript = /)<[^<]*)*<\/script>/gi, + rselectTextarea = /^(?:select|textarea)/i, + rts = /([?&])_=[^&]*/, + rurl = /^(\w+:)?\/\/([^\/?#]+)/, + // Slice function + sliceFunc = Array.prototype.slice, + // Keep a copy of the old load method _load = jQuery.fn.load; @@ -232,15 +240,407 @@ jQuery.extend({ }, // Main method - ajax: function( url , s ) { + // (s is used internally) + ajax: function( url , options , s ) { + // Handle varargs if ( arguments.length === 1 ) { - s = url; - url = s ?
