[英]jquery: function parameter is undefined in success callback
I am trying to access graphList within success callback, but graphList is undefined. 我试图在成功回调中访问graphList,但graphList未定义。 I referred this StackOverflow post. 我提到了这个 StackOverflow帖子。 However, I am not able to access elem. 但是,我无法访问elem。 Any help would be appreciated. 任何帮助,将不胜感激。
getGraphData = function (graphList) {
$.ajax({
type: "GET",
url: 'someURL',
beforeSend: function(xhr){},
success: function(result) {
console.log(result);
console.log(graphList);//undefined
}
});
}
Added creating getGraphList function as below, I can access getGraphList inside success callback 添加了如下创建getGraphList函数,我可以在成功回调中访问getGraphList
var graphList;
var promise = graphInit(response);
promise.done(function(data){
getGraphData(data.graphs)
}
graphInit = function(response,graphList){
getGraphList = function(){return response.graphs;}
}
getGraphData = function (graphList) {
$.ajax({
type: "GET",
url: 'someURL',
beforeSend: function(xhr){},
success: function(result) {
console.log(result);
console.log(graphList);//undefined
graphList = getGraphList();//available
}
});
}
