javascript - t :selectOneMenu how to get selected value using java script?

Question

我想使用java脚本获取选择一个菜单如何获取所选项目值？

<h:outputLabel value="#{l.description1}" styleClass="dataValue" />
<t:selectOneMenu id="chooseLevelTypeId"
    value="#{AssetWizardComptTypeTile.levelTypeId}">
    <f:selectItem itemLabel="" itemValue="0" />
    <f:selectItems value="#{GeneralTables.levelTypesList}" />
    <a4j:support event="onchange" action="#{WizardMainControl.action}"
        ??oncomplete="if (document.getElementById('wizardForm:chooseLevelTypeId').selecteditem == 'somthing') 
        document.getElementById('wizardForm:a1').style.display = 'block';"
        reRender="chooseLevelTypeDesc" />
</t:selectOneMenu>

Answer 1

现在使用 javascript 获取选择的菜单项

var selectedValue = document.getElementById("wizardForm:chooseLevelTypeId").value;

这里的 selectedValue 是您选择的项目。
