From 1070b4aa6c583cb87f67b88afa6896841f70d657 Mon Sep 17 00:00:00 2001 From: Dan Abramov Date: Tue, 17 May 2016 19:05:06 +0100 Subject: [PATCH] Make sure element is reported correctly by tree devtool This adds some tests for getElement() and verifies that it works for text components too. The code that calls the instrumentation is fixed where necessary so that the tests pass. --- .../ReactComponentTreeDevtool-test.js | 4 -- .../ReactComponentTreeDevtool-test.native.js | 3 -- src/renderers/dom/shared/ReactDOMComponent.js | 41 ++++++++++++------- .../stack/reconciler/ReactReconciler.js | 16 ++++---- src/test/ReactComponentTreeTestUtils.js | 20 +++------ 5 files changed, 39 insertions(+), 45 deletions(-) diff --git a/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.js b/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.js index ef5516238a..e0a7692e41 100644 --- a/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.js +++ b/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.js @@ -268,7 +268,6 @@ describe('ReactComponentTreeDevtool', () => { displayName: 'p', children: [{ displayName: 'span', - element: Hi!, children: [{ displayName: '#text', text: 'Hi!', @@ -353,12 +352,10 @@ describe('ReactComponentTreeDevtool', () => { }], }, { displayName: 'Bar', - element: Hi,Mom, children: [{ displayName: 'h1', children: [{ displayName: 'span', - element: Hi,, children: [{ displayName: '#text', element: 'Hi,', @@ -372,7 +369,6 @@ describe('ReactComponentTreeDevtool', () => { }], }, { displayName: 'a', - element: Click me., children: [{ displayName: '#text', text: 'Click me.', diff --git a/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.native.js b/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.native.js index 746f7a82be..4ba5cdc9d9 100644 --- a/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.native.js +++ b/src/isomorphic/devtools/__tests__/ReactComponentTreeDevtool-test.native.js @@ -277,10 +277,8 @@ describe('ReactComponentTreeDevtool', () => { element, children: [{ displayName: 'View', - element: Hi!, children: [{ displayName: 'Text', - element: Hi!, children: [{ displayName: 'RCText', children: [{ @@ -369,7 +367,6 @@ describe('ReactComponentTreeDevtool', () => { displayName: 'View', children: [{ displayName: 'Text', - element: Hi,, children: [{ displayName: 'RCText', children: [{ diff --git a/src/renderers/dom/shared/ReactDOMComponent.js b/src/renderers/dom/shared/ReactDOMComponent.js index 61dc9f87ad..0a8b106837 100644 --- a/src/renderers/dom/shared/ReactDOMComponent.js +++ b/src/renderers/dom/shared/ReactDOMComponent.js @@ -248,16 +248,34 @@ function optionPostMount() { var setContentChildForInstrumentation = emptyFunction;
