@gzx-miller Please provide more details like sample code, any errors from the output pane for typescript, any errors in console etc.

[ramya-rao-a]

@gzx-miller Does the Go to Definition and Find references work in smaller javascript files and just not in bigger files? Or they don't work in any javascript file?

[gzx-miller]

@ramya-rao-a I find this problem have no relation with file size. I'm write the react java-script code. find this problem. but go to define can work well in ts code.

[gzx-miller]

@ramya-rao-a There are more then 85% code oject or function can not go to define. When this problem happen, have a tip"未找到"xxxx"的任何定义", I used china version, so I have no english version tip.

@gzx-miller Please put together a minimal code sample that shows this problem so that we can investigate

[gzx-miller]

@mjbvz I write a demo java-script code based react, please try goto on "this.keyUP"

 var Text = React.createClass({
            getInitialState: function() {
                return {name: "react"};
            },
            keyUp: function(e){
                this.setState({name: e.target.value});
                console.log(this.state.name);
            },
            render: function() {
                return `(`
                    <div className="a">hello wrold{this.state.name}show me
                         <input onKeyUp={this.keyUp} />
                    </div>
                );
            }
        });
        ReactDOM.render(
            <Text></Text>,
            document.getElementById('well')
        );

@mjbvz if you can not reproduce this problem by this code, I can send email to you, please send your email address to my email address.

@ramya-rao-a This problem have no relation with file size.

[mjbvz]

@gzx-miller Thanks for the code

You are running into this TypeScript limitation: microsoft/TypeScript#16184 . TypeScript powers our JavaScript language features and it currently does understand what this refers to inside of object literals. Hopefully this will be fixed with TS 2.5

Closing as upstream

Sounds this issue is about the scenario that if you write React without ES6. When we create a React class by calling React.createReactClass or React.createClass function, the argument looks like a simple JSON but in fact it will be a part of class implementation so that this should point to that object.
