JS构造函数、匿名函数、异步回调

使用JS的构造函数完成公用条件判断，匿名函数完成ajax回调

var Muster = function(){this.flag = falsethis.check= function(){if (!inp[1].value) {message.error(&＃39;数据库地址不能为空&＃39;)} else if (!inp[2].value) {message.error(&＃39;数据库名称不能为空&＃39;)} else if (!inp[3].value) {message.error(&＃39;数据库用户名不能为空&＃39;)} else if (!inp[4].value) {message.error(&＃39;数据库密码不能为空&＃39;)}else{this.flag = true}}this.test = function(callback){var dataURLS = &＃39;jdbc:sqlserver://&＃39; + inp[1].value + &＃39;;databaseName=&＃39; + inp[2].valuevar information = {&＃39;url&＃39;: dataURLS,&＃39;username&＃39;: inp[3].value,&＃39;password&＃39;: inp[4].value}var data = JSON.stringify(information)var options = {url: url + &＃39;testConnection&＃39;,data: data,getresult: function(res) {if (res.result == &＃39;0&＃39;) {if(typeof(callback) == &＃39;function&＃39;){callback()}else{message.success(&＃39;连接成功&＃39;)}} else {message.error(res.data)}}}load2.style.display = &＃39;block&＃39;setTimeout(function() {Ajax.post(options);}, 1000)}this.set = function(){var dataURLS = &＃39;jdbc:sqlserver://&＃39; + inp[1].value + &＃39;;databaseName=&＃39; + inp[2].valuevar information = {"path": inp[0].value,"properties": [{"key": "spring.datasource.url","value": dataURLS},{"key": "spring.datasource.username","value": inp[3].value},{"key": "spring.datasource.password","value": inp[4].value}]}var data = JSON.stringify(information)var options = {url: url + &＃39;setProperties&＃39;,data: data,getresult: function(res) {if (res.result == &＃39;0&＃39;) {message.success(&＃39;修改成功&＃39;)} else {message.error(res.msg + &＃39; [ &＃39; + res.data + &＃39; ] &＃39;)}}}load2.style.display = &＃39;block&＃39;setTimeout(function() {Ajax.post(options);}, 1000)}
}


然后这里写事件调用

btn[0].onclick = function() {muster.flag = falsemuster.check()muster.flag ? muster.test() : &＃39;&＃39;
}
btn[1].onclick = function() {muster.flag = falsemuster.check()muster.flag ? muster.test(muster.set) : &＃39;&＃39;
}
