如何在JSF中将Javascript的结果动态保存到Bean中?

但是我想将这个自动完成操作的结果保存到我的bean属性propertyC.property.street
中
我该怎么做呢?试试看
document.getElementById(panel:searchTextField).value = <value you need to set>.
document.getElementById(面板:searchTextField)。值=。
输入组件需要进入表单组件内部,当通过JS方式更改值并依赖change
事件时,还应该通过对HTML DOM元素的onchange()
函数调用手动触发事件
因此,在表单中:
<h:form id="searchForm">
<h:inputText id="searchTextField" value="#{propertyC.property.street}" size="100">
<f:ajax listener="#{propertyC.showAddress}" />
</h:inputText>
</h:form>
你想在
place\u change
event fire时保存吗?实际上,我不知道哪个变量包含从自动完成列表中选择的新值。在你的情况下:google.maps.event.addListener(自动完成,'place\u changed';…var place\u dest=autocomplete.getPlace();var vlocation=place_dest.geometry.location;//value
不是一个NamingContainer
组件,更不用说JSF组件了。它只是一个基本的HTML,基本上是JSF.BalusC的纯模板文本,出于某种原因,如果我把输入
放在表单
中,就像你所建议的那样,映射根本不起作用re,只有在表单外部它才起作用,但我无法获得所选的值。我关心表单中的id
,如您所示替换前缀,但到目前为止什么都没有。
var input = document.getElementById("searchForm:searchTextField");
input.value = newvalue;
input.onchange();
