问题 I read High Performance Web Sites: Essential Knowledge for Front-End Engineers and in it the author suggests that all JavaScript code should be externalized and put at the bottom of the page instead of putting it in the head. This is illustrated in this example. The external script tag blocks both downloading and progressive rendering of a page, so the solution was to put it at the bottom of the page. However, in his second book Even Faster Web Sites: Performance Best Practices for Web

问题 Let's say that I have this string: s = '<p>Hello!</p>' When I pass this variable to a template, I want it to be rendered as raw html. Looking at the docs I see that I can either use the safe filter: {{s|safe}} or disable autoescape: {%autoescape off} {{s}} {%endautoescape%} or inside the python code declare it safe: from django.utils.safestring import mark_safe s = mark_safe(s) None of these options are working for me. Whatever I do, the string is displayed as: <p>Hello!</p> I must be missing

问题 I am working on a code that generates PDF containing arabic texts. For each character, I am choosing the correct glyph in the presentation forms to display the text correctly. This works fine but Unicode doesn't contain presentation form of all arabic characters. For example \u067D ARABIC LETTER TEH WITH THREE DOTS ABOVE DOWNWARDS ٽ. There is no presentation form of this character even though the character has medial form, as can be seen in this string: لٽط What is the reason that

问题 On app startup, all children of the LinearLayout (LL) are rendered. But, with the same code when coming from another activity, no children of the LL are visible, nevertheless included in the view tree. See: The activity_main.xml is: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:id="@+id

问题 In my header component, I have conditional rendering set to display different links depending on if the user is logged in or not. The conditional rendering works fine EXCEPT the fact that it blinks one set of links before displaying the proper set of links. It dawned on me this is because of the axios.get call I have that retrieves the user's status. The state variable is initially set to false. If the user is logged in, the get call will indicate that and the state variable will get set to

问题 I am using react-table plugin, and my cells keep re-rendering while I am changing the applied searching filter even though their values aren't changed. As seen in the video, name and debt TDs keep updating, even though their values are static. https://i.imgur.com/2KkNs9f.mp4 I imagine, that may impact performance on larger tables. Is there any fix? Or am I doing anything wrong? Thanks. Edit: Code has been requested. Not much to show, basically everything done as in documentation. Rendering

问题 I've been banging my head against this for a while but I cannot figure out if it is possible to create a DepthMask shader for HDRP (as descibed here). For my exact use, I'm trying to create a "hole" in the shape of whatever I have the material applied to, that shows the contents of a different camera rendered behind everything. I tried messing around with the render queue within the shader, different ZTest and ZWrite combinations, as well as some variations of the shader I found. On top of
