In an object I have a method where I want to get some information from a server(JSON format). I want to add this data to my object where the function is (By using a setter). The problem is that this isn't my object but the jquery callback. How could/should I solve this?
function anObject() {
$.get(URL, doTheCallback);
function setExample(example) {
this.example = example;
}
function doTheCallback(data) {
this.setExample(data.results[0].example);
}
}
You can use bind:
$.get(URL,doTheCallback.bind(this));
The
bind()method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.
Or assign your scope in a variable like:
function anObject() {
var that = this;
$.get(URL, doTheCallback);
function setExample(example) {
that.example = example;
}
function doTheCallback(data) {
that.setExample(data.results[0].example);
}
}
If you switched to $.ajax, you can use the context option.
function anObject() {
$.ajax(URL, {context: this}).done(doTheCallback);
function setExample(example) {
this.example = example;
}
function doTheCallback(data) {
this.setExample(data.results[0].example);
}
}
