From 9aef9a2324fc1a1951e470c645df6c1b11a5ffdc Mon Sep 17 00:00:00 2001 From: Jacob Hoffman-Andrews Date: Sun, 21 Nov 2021 00:24:38 -0800 Subject: [PATCH] Inhibit clicks on summary's children A byproduct of using `
` and `` to show/hide detailed documentation was that clicking any part of a method heading (or impl heading) would show or hide the documentation. This was not super noticeable because clicking a link inside the method heading would navigate to that link. But clicking any unlinked black text in a method heading would trigger the behavior. That behavior was somewhat unexpected, and means that if you try to click a type name in a method heading, but miss by a few pixels, you get a confusing surprise. This change inhibits that behavior by putting an event listener on most summaries that cancels the event unless the event target was the summary itself. In practice, that means it cancels the event unless the target was the "[+]" / "[-]", because the rest of the heading is wrapped inside a `
`, which is the target for anything that doesn't have a more specific target. --- src/librustdoc/html/static/js/main.js | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/librustdoc/html/static/js/main.js b/src/librustdoc/html/static/js/main.js index 4b55a0a69b663..908d3f65fd35b 100644 --- a/src/librustdoc/html/static/js/main.js +++ b/src/librustdoc/html/static/js/main.js @@ -886,6 +886,14 @@ function hideThemeButtonState() { } }); + onEachLazy(document.querySelectorAll(".rustdoc-toggle > summary:not(.hideme)"), function(el) { + el.addEventListener("click", function(e) { + if (e.target.tagName != "SUMMARY") { + e.preventDefault(); + } + }) + }); + onEachLazy(document.getElementsByClassName("notable-traits"), function(e) { e.onclick = function() { this.getElementsByClassName('notable-traits-tooltiptext')[0]
