jQuery扩展ajaxName
jQuery扩展ajaxName,用于ajax提交方法的页面数据获取，根据页面元素的name生成相应的js对象，然后可以把这个对象传给JSON编码库进行编码向后台提交，支持数组，支持.表达式/* * jQuery Ajax By Name Plugin * * licensed under the MIT licenses: * http://www.opensource.org/licenses/mit-license.php * * Author achun (achun.shx at gmail.com) * Create Date: 2008-6-21 * Last Date: 2008-6-21 * Revision:2.8.6.21 */(function($) {/** * 获取鼠标点击的元素坐标 */$.fn.clickPos = function(e){var pos ={x:0,y:0};if (e.offsetX != undefined) { pos.x = e.offsetX; pos.y = e.offsetY;} else if (typeof $.fn.offset == 'function') { var offset = this.offset(); pos.x = e.pageX - offset.left; pos.y = e.pageY - offset.top;} else { pos.x = e.pageX - this.offsetLeft; pos.y = e.pageY - this.offsetTop;}return pos;}/** * ajaxName() 根据标签name属性来提交数据,替代form提交方式 * options:{//与ajax的options是一样的结构 *data:{}//要附加提交的数据 * } * successful:如果元素有有效值,defualt:true */$.fn.ajaxName = function(options,successful) {if(options==undefined) options={};options.data = options.data || {};successful = successful == undefined ? true:successful;var data = {};var name= options.name || '';this.each(function() {var el=this,o=$(this),n = o.attr('name'),hasval = o.attr('value')!=undefined;if (!n) return;var t = el.type, tag = el.tagName.toLowerCase();if (n=='/'){if (name=='') name = hasval?o.attr('value'):o.text();return;} if (successful && (el.disabled || t == 'reset' || t == 'button' || (t == 'checkbox' || t == 'radio') && !el.checked || (t == 'submit' || t == 'image') || tag == 'select' && el.selectedIndex == -1)) return; var v= hasval? o.attr('value') :o.hasClass('ValueByText')?o.text():o.html(); if (v == undefined) return;if (n.indexOf('.')>0){ n=n.split('.'); var len=n.length - 1; var b=data; $.each(n,function(i){ if (i!=len){ if(b == undefined) b={}; b=b; }else b=v; });}else if (n.indexOf('[]')>0){ n=n.slice(0,n.length-2); if(data == undefined) data=[]; data.push(v);}else{data=v;}});var dat={};if (name){dat=data;data=dat;}elsedat=data;for (var o in options.data){data=options.data;};options.data=dat;return options.data;};})(jQuery);
