<h:body>
    <div id="panel" style="margin-left: -260px">
        <h:inputText id="searchTextField" value="#{propertyC.property.street}" size="100" >
            <f:ajax listener="#{propertyC.showAddress}" />
        </h:inputText>
    </div>

    <div id="map-canvas"></div>

</h:body>
</html>

But I want to save, the result of this autocomplete operation into my bean attribute propertyC.property.street.

How can I do that ?

输入组件需要进入表单组件内部,当通过 JS 方式改变值并依赖change事件时,还应该通过onchange()HTML DOM 元素上的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>

并相应地修复 JS 代码以包含表单 ID 并触发更改事件:

var input = document.getElementById("searchForm:searchTextField");
input.value = newvalue;
input.onchange();

尝试

document.getElementById(panel:searchTextField).value = <value you need to set>.
