From b59c94d5c23c0b1ec4b2506be0aed6b0578f19f3 Mon Sep 17 00:00:00 2001 From: John Resig Date: Sun, 9 Sep 2007 19:00:56 +0000 Subject: [PATCH 1/1] So, apparently, I never committed the second half of the new field value code. This allows you to set values on groups of checkboxes, radio buttons, and selects. --- src/core.js | 55 ++++++++++++++++++++++++++++++++++++++++++------------- 1 file changed, 42 insertions(+), 13 deletions(-) diff --git a/src/core.js b/src/core.js index ac45d62..67cb147 100644 --- a/src/core.js +++ b/src/core.js @@ -292,31 +292,60 @@ jQuery.fn = jQuery.prototype = { val: function( val ) { if ( val == undefined ) { - if ( this.length ) { - var elem = this[0]; + if ( this.length ) { + var elem = this[0]; - // We need to handle select boxes special if ( jQuery.nodeName(elem, "select") ) { var index = elem.selectedIndex, + // We need to handle select boxes special + if ( jQuery.nodeName(elem, "select") ) { + var index = elem.selectedIndex, a = [], options = elem.options, one = elem.type == "select-one"; - // Nothing was selected if ( index < 0 ) - return null; - - // Loop through all the selected options for ( var i = one ? index : 0, max = one ? index + 1 : options.length; i < max; i++ ) { - var option = options[i]; if ( option.selected ) { // Get the specifc value for the option var val = jQuery.browser.msie && !option.attributes["value"].specified ? option.text : option.value; + // Nothing was selected + if ( index < 0 ) + return null; + + // Loop through all the selected options + for ( var i = one ? index : 0, max = one ? index + 1 : options.length; i < max; i++ ) { + var option = options[i]; + if ( option.selected ) { + // Get the specifc value for the option + var val = jQuery.browser.msie && !option.attributes["value"].specified ? option.text : option.value; - // We don't need an array for one selects if ( one ) + // We don't need an array for one selects + if ( one ) return val; - // Multi-Selects return an array a.push(val); } } - return a; + // Multi-Selects return an array + a.push(val); + } + } + + return a; - // Everything else, we just grab the value } else + // Everything else, we just grab the value + } else return this[0].value.replace(/\r/g, ""); } } else - return this.attr( "value", val ); + return this.each(function(){ + if ( val.constructor == Array && /radio|checkbox/.test(this.type) ) + this.checked = (jQuery.inArray(this.value, val) >= 0 || + jQuery.inArray(this.name, val) >= 0); + else if ( jQuery.nodeName(this, "select") ) { + var tmp = val.constructor == Array ? val : [val]; + + jQuery("option", this).each(function(){ + this.selected = (jQuery.inArray(this.value, tmp) >= 0 || + jQuery.inArray(this.text, tmp) >= 0); + }); + + if ( !tmp.length ) + this.selectedIndex = -1; + } else + this.value = val; + }); }, html: function( val ) { -- 1.7.10.4
