我有一个 js 函数codeAddress()，它处理来自 and 的数据并address更新其值。和 的数据被传递给后备 bean，但 setter 方法似乎被调用了一个延迟的请求。末尾的 显示正确的新数据。 什么时候一切正常，支持 bean setter 方法被调用，它们应该没有任何延迟。 我不知道这里可能出了什么问题。fullAddressvalidField
fullAddressvalidField<p:ajax>
alert()codeAddress
addressonchange="test()"

我的 JS：

function initialize() {
    geocoder = new google.maps.Geocoder();

function test(){

function codeAddress() {

这不是一个重复的问题。
第一个错误是<p:ajax>用于提交将由 JS 更改的数据，因为在脚本仍在运行时已经准备好 ajax 请求。第二个错误是使用 non-cross-browser-compatible jsf.ajax.request。现在我只是删除了<p:ajax>jQuery 并使用了一个解决方案。这个函数只是从地理编码器回调函数中调用的：

function jsfSubmit(){
    document.getElementById('addressForm:fullAddress').value = fullAddress;
    document.getElementById('addressForm:validField').value = valid;
    $.ajax({type:'POST', data:$('#addressForm').serialize(), success: function(response) {
        if(valid){
            var destPage = 'nextPage.xhtml';
            window.location = destPage;
        }
    }});
};
