废话不多说，直接上代码
(function (window) { var arr = []; var VP = function (selector, context) { return new VP.fn.init(selector, context); } VP.fn = VP.prototype = { constructor: VP, init: function (selector, context) { var _document = window.document, elem, mark = selector.charAt(0); if (mark == '#') { elem = _document.getElementById(selector.substring(1)); if (elem) { this[0] = elem; this.length = 1; } } return this; }, splice: arr.splice, }; VP.extend = VP.fn.extend = function () { var options, name, src, copy, copyIsArray, clone, target = arguments[0] || {}, i = 1, length = arguments.length, deep = false; if (typeof target === "boolean") { deep = target; target = arguments[i] || {}; i++; } if (typeof target !== "object" && !VP.isFunction(target)) { target = {}; } if (i === length) { target = this; i--; } for (; i < length; i++) { if ((options = arguments[i]) != null) { for (name in options) { src = target[name]; copy = options[name]; if (target === copy) { continue; } if (deep && copy && (VP.isPlainObject(copy) || (copyIsArray = VP.isArray(copy)))) { if (copyIsArray) { copyIsArray = false; clone = src && VP.isArray(src) ? src : []; } else { clone = src && VP.isPlainObject(src) ? src : {}; } target[name] = VP.extend(deep, clone, copy); } else if (copy !== undefined) { target[name] = copy; } } } } return target; }; VP.fn.extend({ get: function () { return this[0]; }, }); VP.fn.init.prototype = VP.fn; window.VP = VP; })(window);
以上这篇JQuery 获取Dom元素的实例讲解就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
