Keeping selected an option in select dropdown with jquery after refresh

由 隐身守侯 提交于 2019-12-13 05:33:10
问题 I have small script that reloads a select containing the nicknames of the users in a chatroom. When someone clicks the select, the javascript refreshes it, repopulating the option from a php page to add people that have logged in and removing those who logged out. The script works properly on reloading the select, but I want it to avoid losing the precedent selected option if a user clicks the select another time to refresh the list, and the script doesn't keep the correct option. All the

问题 I have a html/php script which prints a text string directly to the page. However when I refresh the page that text is still there. I've googled this and check this forum too and tried various suggestions e.g. <input autocomplete="off"> and <body onload="document.FormName.reset();"> etc. None of them work. The php code that prints the string is (if regex matches serial number then execute command else print error string): if (preg_match($snregex, $sn, $matches)) { <command> } else { echo

ReactJS: reloading/re-rendering a component on click

由 帅比萌擦擦* 提交于 2019-12-13 04:12:38
问题 I have a component called "categories", where I have 2 buttons active and inactive. Each button calls an api to either activates or deactivates the selected record. However, the button part and the api part are running completely fine and getting proper response after getting the task done. But, I need the "categories" component to reload/re-render after the api response has returned the success code. I googled for the solution but the answers I got were little confusing for me because I am

What is the mechanism that causes the page to refresh when data is submitted to the server?

问题 Why exactly does the page refresh when data is sent from a form element to the server? For data that is sent by POST for example, does what the server receives depend on how it was sent? i.e. by simple form submit, DOM submit, ajax submit, etc. Is it the server response that triggers the refresh? Is there any way to change the response that is sent so that it doesn't trigger a refresh? Or prevent a response from being sent at all? P.S. I am aware that there are a gazillion different ways that

flipclock.js resets on refresh after time expires

由 夙愿已清 提交于 2019-12-13 03:04:19
问题 I'm using Flipclock.js on a local page. Everything works fine, except after the countdown reaches 0. This page is used in a display in my office. I rotate between this an 2 other pages. Every time the page reloads after the timer reaches 0 the dates and time get screwy. Here is the code: var clocks = []; $(document).ready(function() { var currentDate = new Date(); var futureDate = new Date(currentDate.getFullYear() +0, 10, 14, 12, 31); var diff = futureDate.getTime() / 1000 - currentDate

How to reload an IFrame every x seconds?

由 社会主义新天地 提交于 2019-12-13 01:17:03
问题 Was wondering how I can reload an iframe every x seconds, perferably not using javascript. Thanks. 回答1: With a Refresh: x HTTP header or with an HTML element in the document loaded into the iframe: <meta http-equiv="refresh" content="x" /> This element should be placed inside of the document's <head/> element. If you do not have control over the document loaded into the frame or the server that it is served from, you have two options: JavaScript. Write another HTML page with the above <meta/>

EclipseLink persistence and refresh both association entities

由 百般思念 提交于 2019-12-13 00:36:00
问题 I'm using EclipseLink in my Java EE project with a PostgreSQL database. I have trouble finding the right annotations for a correct behaviour when I persist/refresh entities which are part of oneToMany/manytoOne associations. For example, I have an entity "Project" which is first created by the users through a UI. Then the users can add "Analysis" into the project they created. Hence, an analysis is part of one project and a project can have several analysis. The persist action works fine (I
