我正在尝试使用jQuery验证插件来检查可用的名称。它将请求发布到php文件,并得到响应0或1。
问题是我无法将结果传递给主函数。请看下面的代码
jQuery.validator.addMethod("avaible", function(value, element) {
$.post("/validate.php", {
friendly_url: value,
element:element.id
}, function(result) {
console.log(result)
});
//How to pass result here???
console.log(result)
}, "");
正如人们已经说过的,它是异步的,并且是myOtherFuntion
:-)
我只是把这些评论合并成某种答案:
function myOtherFunction(result) {
// here you wrote whatever you want to do with the response result
//even if you want to alert or console.log
alert(result);
console.log(result);
}
jQuery.validator.addMethod("avaible", function(value, element) {
$.post("/validate.php", {
friendly_url: value,
element:element.id
}, function(result) {
myOtherFunction(result);
});
//How to pass result here???
//there is no way to get result here
//when you are here result does not exist yet
}, "");
由于Javascript的异步特性,console.log(result)
将无法工作,因为服务器尚未返回结果数据。
jQuery.validator.addMethod("avaible", function(value, element) {
$.post("/validate.php", {
friendly_url: value,
element:element.id
}, function(result) {
console.log(result);
doSomethingWithResult(result);
});
function doSomethingWithResult(result) {
//do some stuff with the result here
}
}, "");
以上内容将允许您将结果传递给另一个函数,该函数将允许您在结果从服务器返回后访问和处理结果。
