问题 I want to invalidate cached app.js after every single release. Short question : Is it necessary to physically rename(by gulp-rev, for example) app.js to app-a23ds.js every time or is enough to add param with hash in html like app.js?_=<build number> Description : I was sure before that is enought to write something like app.js?_=<build number> in index.html to load new file instead of cahed. But when I'm investigate this question deeper I found a few of huge solutions for this case. Like gulp

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago .

It was certainly nice to learn Python, but I found out there has just been a Great Python Rewrite too late, so I had to learn both Python 3 and 2.6 essentially. I'm a newbie, so I'd like people to share what they think the strengths/weaknesses of Python 3 are from the perspective of those who do end-user programming rather than language designers. My question would be more of what people are

问题 I want to display like an error with red color unless there is a selected option. Is there any way to do it. 回答1: For setting a required Select field with Material UI, you can do: class SimpleSelect extends React.Component { state = { selected: null, hasError: false }; handleChange(value) { this.setState({ selected: value }); } handleClick() { this.setState({ hasError: false }); if (!this.state.selected) { this.setState({ hasError: true }); } } render() { const { classes } = this.props; const

问题 I come from traditional back-end Java/Spring environment to learn Angular 2 framework , and have hard time to grasp many of the fundamental concepts.

问题 I am working on a site where I have a frontend registration form and it works as it should but now I am having difficulty with automatic login and redirect upon successful registration. I've tried a few plugins and codes in my themes functions file but none seem to work. So how can I automatically log a person in after a successful registration?

问题 I have created dropdown list which gives suggestions from existing data (like google search). I have followed the steps mentioned in the link to get the expected result. I have changed the process to VBA Code since the column range that has data can increase in time (Formula will be inserted for a range dynamically when a new entry is added).
