POST 实现

发现这个脚本不支持 POST 功能，于是自己动手实现，不能总是当伸手党。考虑到网上修改版本已经不少了，所以就不再弄一个自己的修改版了。
修改部分代码如下，“是基于原版修改的”。要不要考虑加上去：
			// ...
				{name: "维普",
					url: /^http:\/\/lib\.cqvip\.com\/zk\/search\.aspx/,
					enabled: true,
					engineList: "scholar",
					style: '\
						width: 960px;\
						height: 26px;\
						overflow: hidden;\
					',
					insertIntoDoc: {
						keyword: function () {
							var inputKeyword = $('input#b_Text0') .val() .trim();
							if (inputKeyword) {
								return inputKeyword;
							}

							var exp = $('div.search_gs') .text();

							var startStr = '题名或关键词=';								
							var startIndex = exp.indexOf(startStr);
							if (startIndex == - 1) {
								return '';
							}

							var endIndex = exp.indexOf(' 与 ');
							if (endIndex == - 1) {
								endIndex = exp.length;
							}

							var keyword = exp.slice(startIndex + startStr.length, endIndex);
							return keyword;
						},
						target: 'css;div.search',
						where: 'beforeEnd',
					},
				},

			// ...
			
			engineList.scholar[3] = { // 维普
				name: '维普',
				url: 'http://lib.cqvip.com/zk/search.aspx',
				method: 'POST',
				args: {
					'E': '(Keyword_C=%s+Title_C=%s)',
					'H': '题名或关键词=%s 与 范围=全部期刊'
				},
				favicon: 'data:image/png;base64,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',
