Is there a way to properly pass the context of
Test = function(){
this.x = //(1) How do I access 'this' in the return statement?
this.line = d3.svg.line()
.interpolate("linear")
.x(function (d) {
return this.x(d.x);
})
}
Though using 'this.x' in the return does not provide the desired context as indicated in (1), How can I correctly access it within the return statement?
To ensure the function is bound to the current object, you can use Function.prototype.bind. Here's an example:
this.line = d3.svg.line()
.interpolate("linear")
.x(function (d) {
return this.x(d.x);
}.bind(this))
By binding the anonymous function to the current object using this, within the function, this will correctly refer to the bound value.
Another common approach is to store a reference to the this object like so:
Test = function() {
var that = this; // Store a reference to `this`
this.x = 1;
this.line = d3.svg.line()
.interpolate("linear")
.x(function(d) {
return that.x(d.x); // Use `that` instead of `this`
})
}
