问题 Following up on this question regarding reloading a module, how do I reload a specific function from a changed module? pseudo-code: from foo import bar if foo.py has changed: reload bar 回答1: What you want is possible, but requires reloading two things... first reload(foo) , but then you also have to reload(baz) (assuming baz is the name of the module containing the from foo import bar statement).

由 拥有回忆 提交于 2019-11-26 09:24:26
问题 I want to reload a page using: window.location.reload(true); But I receive the POSTDATA warning because the refresh function want to resend previous POST form data. How can I refresh my page without this warning? UPDATED: I have no control of the project! I can\'t workaround the POST itself! 回答1: Just changing window.location in JavaScript is dangerous because the user could still hit the back button and resubmit the post, which could have unexpected results (such as a duplicate purchase ).

javascript location.hash refreshing in IE

由 馋奶兔 提交于 2019-11-26 08:08:45
问题 I need to modify the hash, remove it after certain processing takes place so that if the user refreshes they do not cause the process to run again. This works fine in FF, but it seems that IE is reloading every time I try to change the hash. I think it is related to other things that are loading on the page, though I am not certain. I have an iframe that loads (related to the process) as well as some scripts that are still being fetched in the parent window. I can\'t seem to figure out a good

问题 I\'m trying to make a live, in-page css editor with a preview function that would reload the stylesheet and apply it without needing to reload the page. What would be the best way to go about this? 回答1: On the "edit" page, instead of including your CSS in the normal way (with a <link> tag), write it all to a <style> tag. Editing the innerHTML property of that will automatically update the page, even without a round-trip to the server. <style type="text/css" id="styles"> p { color: #f0f; } <

问题 How might I capture the page reload event? I have a messaging system which loses all its input when the user refreshes the page. I want to use ajax to re-populate, hence my need to detect when the page has been refreshed/reloaded. 回答1: $('body').bind('beforeunload',function(){ //do something }); But this wont save any info for later, unless you were planning on saving that in a cookie somewhere (or local storage) and the unload event does not always fire in all browsers. Example: http:/

问题 How can I force the web browser to do a hard refresh of the page via JavaScript?

Prevent Page Load on Jquery Form Submit with None Display Button

由 淺唱寂寞╮ 提交于 2019-11-26 02:16:58
I have a chatbot of sorts set in MSDOS terminal style. The user types their response then hits enter. I have found that when I tag the button with "display: none;" it causes the page to reload on several browsers (my windows chrome browser doesn't reload. not sure why). How can I have the button hidden yet the form and code functioning properly? I would rather not use "position: absolute;" to send it off screen. HTML: <div id="bot"><form> <input id="user-response" type="text" placeholder="" autocomplete="off" autofocus /> <button id="user-submit" type="submit">Send</button> </form></div>
