取得URL上get參數的值

Thank you for reading this post, don't forget to subscribe!

透過URL抓取?(問號)以後的參數值

function getURLVar(key) {
	var value = [];
	var query = String(document.location).split('?');

	if (query[1]) {
		var part = query[1].split('&');
		for (i = 0; i < part.length; i++) {
			var data = part[i].split('=');
			if (data[0] && data[1]) {
				value[data[0]] = data[1];
			}
		}

		if (value[key]) {
			return value[key];
		} else {
			return '';
		}
	}
}
