Template literals syntax is not working in IE11

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-17 12:14:06
问题 The back-tick character is not recognized as a Valid Character in IE11 when using the "use strict" directive while it works in other browsers, such as Chrome. What is the interpretation of this behavior taking into consideration that IE11 is still widely used even among Windows 10 users?? "use strict"; function doIt() { let tt; tt = 50; alert(`${tt}`); alert("test"); } doIt(); Error: { "message": "Invalid character", "filename": "http://stacksnippets.net/js", "lineno": 18, "colno": 17 } 回答1:

问题 const perunString = perun.times(100).toFixed(2).toString(); return `%{perunString} %`; Which gives two errors 'perunString' is defined but never used Strings must use single quotes 回答1: You have an error in your template interpolation syntax that is probably causing both errors: // Before `%{perunString} %` // After `${perunString} %` Note the change from %{ to ${ . 来源： https://stackoverflow.com/questions/36162158/eslint-not-recognizing-template-literal

styled-components, polished and themes

由 笑着哭i 提交于 2019-12-11 09:46:41
问题 I am trying Styled-components in a simple React project, I have a theme object that is passed to the component so I can do: background-color: ${props => props.theme.primary}; I am also using Polished to modify the passed values, so a button uses a darker version of the color as an outline. I can do this with: border: 1px solid ${darken(0.05, '#00823b')}; But I need the color value to be from the theme, how do I go about passing the theme properties in? Thanks! 回答1: Define your border style

Nesting template strings in Typescript

由 岁酱吖の 提交于 2019-12-11 06:57:20
问题 I'm trying to retrieve a variable from an object. cell: (row: any) => `${row.testcolumn}` My only issue is that I don't know what 'testcolumn' is ahead of time as I'm doing this dynamically. I'm not sure what to do, and the nested template string strategy I'm attempting will not compile. cell: (row: any) => `${row.(`${varString}`)}` I've also tried just using the variable name instead of nesting a template string, but that just looks for the varString value in the object, which doesn't exist.

Template html and template string in web components

问题 Is it better to use html template (and then html import) to create web components or to use template string? What are pros and cons of these methods? 回答1: Using html template files is better for reuse: the same file can be used in different web components. Also they are better displayed in most IDEs as they are recognized as full HTML code. Using template strings is faster (inline). They don't rely on HTML Imports which is not adopted by every browser vendors. Also you can use template

问题 In GraphQL you can write something like this to define a query: const USER_QUERY = gql` { user(id: 2) { name } } ` In styled components you can define a styled component like this: const Button = styled.button` background-color: papayawhip; ` What is this syntax?

问题 I've been trying to solve this problem for 3 days already but I can't seem to find any extension to have syntax highlighting for strings that used backticks(I don't know what is the general term for this kind of strings). But if there are no extensions to enable syntax highlight for this kind of strings, is there any settings for vscode that enables me to syntax higlight? 回答1: To follow-up on Matt Bierner's previous answer. You should use this Visual Studio Code extension: angular2-inline

Are ES6 template literals safer than eval?

由 不羁岁月 提交于 2019-12-04 16:00:18
问题 Template literals smell a bit like eval to me, and it's often cited that using eval is a bad idea. I'm not concerned with performance of template literals, but I am concerned about injection attacks (and other security concerns I may not be thinking of). Edit An example of something that feels odd to me let ii = 1; function counter() { return ii++; } console.log(`${counter()}, ${ii++}, ${counter()}`); Which outputs 1, 2, 3 The template literal is making side effects at the global level.
