JS实现URL参数添加删除功能
JS实现URL参数添加删除功能,在线演示。HTML使用范例:
<html> <head> <script src="jquery-3.0.0.min.js"></script> <script src="url-param.js"></script> </head> <body> <span class="add" target="tag" value="1">添加</span><br /> <span class="add" target="tag" value="2">修改</span><br /> <span class="delete" target="tag" value="3">删除</span><br /> <span class="add" target="key" value="a">添加另外一条</span><br /> <script> $(".add").on("click", function() { var target = $(this).attr("target"); var value = $(this).attr("value"); webUI.addParama(target, value); }) $(".delete").on("click", function() { var target = $(this).attr("target"); webUI.delParama(target); }) </script> </body> </html>
Javascript代码:
var webUI = { //添加url参数 addParama: function(key, val) { var search = window.location.search; if (search.indexOf('?') != -1) { search = search.substring(1); var search_arr = search.split('&'); var url_arr = []; var exists = 0; for (var i = 0; i < search_arr.length; i++) { if (!search_arr[i]) continue; var temp = search_arr[i].split('='); if (key == temp[0]) { exists = 1; url_arr.push(key + '=' + val); } else { if (temp[0] != 'page' && temp[0] != 'token') { url_arr.push(search_arr[i]); } } } if (!exists) url_arr.push(key + '=' + val); url = window.location.pathname + '?' + url_arr.join('&'); } else { url = window.location.pathname + '?' + key + '=' + val; } window.location.href = url; }, /* * 添加url参数 * jsonArr: 添加参数数组 * delArr: 删除参数数组 * demo: webUI.addMultiParama([{'key':'from', 'val':from}, * {'key':'to', 'val':to}], [{'key':'recently'}]); */ addMultiParama: function(jsonArr, delArr) { var delArr = delArr || []; var search = window.location.search; if (search.indexOf('?') != -1) { search = search.substring(1); var search_arr = search.split('&'); var url_arr = []; var update_arr = []; //del parama if (delArr.length > 0) { for (var i = 0; i < search_arr.length; i++) { var temp = search_arr[i].split('='); for (var j = 0; j < delArr.length; j++) { if (temp[0] == delArr[j].key) { search_arr.splice(i, 1); } } } } //判断未添加的情况 for (var j = 0; j < jsonArr.length; j++) { var exists = 0; for (var i = 0; i < search_arr.length; i++) { if (!search_arr[i]) continue; var temp = search_arr[i].split('='); if (jsonArr[j].key == temp[0]) { exists = 1; } } if (!exists) { url_arr.push(jsonArr[j].key + '=' + jsonArr[j].val); } else { update_arr.push({'key': jsonArr[j].key, 'val': jsonArr[j].val}); } } for (var i = 0; i < search_arr.length; i++) { if (!search_arr[i]) continue; var temp = search_arr[i].split('='); var update = 0; for (var j = 0; j < update_arr.length; j++) { if (update_arr[j].key == temp[0]) { update = 1; url_arr.push(update_arr[j].key + '=' + update_arr[j].val); } } if (!update) { if (temp[0] != 'page' && temp[0] != 'token') { url_arr.push(search_arr[i]); } } } } else { var url_arr = []; for (var j = 0; j < jsonArr.length; j++) { url_arr.push(jsonArr[j].key + '=' + jsonArr[j].val); } } url = window.location.pathname + '?' + url_arr.join('&'); window.location.href = url; }, //del url 参数 delParama: function(key) { var search = window.location.search; if (search.indexOf(key) != -1) { search = search.substring(1); var search_arr = search.split('&'); var url_arr = []; for (var i = 0; i < search_arr.length; i++) { var temp = search_arr[i].split('='); if (key != temp[0]) { url_arr.push(search_arr[i]); } } url = window.location.pathname + '?' + url_arr.join('&'); } window.location.href = url; } };
非常好用。
