How to change h:outputText value by JavaScript?
提问by Peter
I already tested with 2 inputText, It runs well for example
我已经用 2 个 inputText 进行了测试，例如它运行良好
var tdate = document.getElementById('txtDate'); //h:inputText
var tdt = document.getElementById('txtDateTime'); //h:inputText
tdate.onchange = function(){
tdt.value = tdate.value;
};
How can I change the value of " tdt " - h:outputText?
如何更改“tdt”-h:outputText 的值？
var tdate = document.getElementById('txtDate'); //h:inputText
var tdt = document.getElementById('txtDateTime'); //h:outputText

Look in the generated HTML source. Rightclick page in browser and view source. You'll see that the <h:outputText>renders a HTML <span>element with the value in its body. To alter the body of a <span>in JavaScript you need to manipulate the innerHTML.
查看生成的 HTML 源代码。在浏览器中右键单击页面并查看源代码。您将看到<h:outputText>渲染了一个 HTML<span>元素，其正文中包含该值。要<span>在 JavaScript 中更改 a 的主体，您需要操作innerHTML.
tdt.innerHTML = "new value";
