How to execute JavaScript after page load?

由 梦想的初衷 提交于 2019-12-17 19:32:56
问题 I would like to execute a JavaScript function after the page was loaded. At the moment I have a commandButton and everything works fine. However it would be more comfortable if the user is not supposed to hit the button. I have tried f:event, but I do not have a listener, I have only the JavaScript function. Moreover body onload does not work for me as I use only high level components. <f:view xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http:/

How to use jsf.ajax.request to manually send ajax request in JSF

由 删除回忆录丶 提交于 2019-12-17 18:44:08
问题 I have a table and each row has the 'onclick' configured to call a js function - this part works. I would like the function to issue an ajax request to a method that I can somehow define. Upon return, a div below the table should be rendered. Is this possible? I tried the JS function with the code: <h:outputScript library="javax.faces" name="jsf.js" /> ... function clickAndRender() { jsf.ajax.request(this, event, {render: 'div-to-render'}) } But it doesn't work of course. I have no idea what

JSF f:ajax listener vs commandButton action

由 ぐ巨炮叔叔 提交于 2019-12-17 18:27:45
问题 I'm curious what is the difference between these two ways of executing ajax calls: <h:commandButton value="Submit" action="#{bean.action}"> <f:ajax execute="@form" render="component"/> </h:commandButton> and <h:commandButton value="Submit"> <f:ajax listener="#{bean.action}" execute="@form" render="component"/> </h:commandButton> It appears that people use the first way more often, but the second seems to work just fine as well... 回答1: The first way allows for navigation by returning a String

Primefaces DataTable + JPA / Hibernate Pagination

由 拈花ヽ惹草 提交于 2019-12-17 17:54:08
问题 It'll be so cool if i can somehow combine both of these framework together in pagination. Clicking on the next or prev button on the Primefaces Datatable will trigger the query, limiting the query result using JPA. Also perhaps with some mechanism, the primefaces component can also get the total pages from another JPA select count query ? Is there any example on how to put these into work ? Please share your experiences on this. Thank you ! 回答1: You can use a LazyDataModel. In this sample I'm
