意外错误:执行JavaScript/Reference错误

Question

我没有对这个数据库进行任何更改,突然间,我在加载各种Xpages时出现(500)错误.在这个,当我在数据库属性的xpages选项卡上切换到"显示Xpage运行时错误"时,它会在web下面显示错误.

如果我删除了包含此客户端代码的按钮(它之前已经完美地验证了编辑框),则错误只会移动到页面上的下一段JavaScript并产生类似的错误.

我试过"清理"项目.我试图用服务器ID签署整个数据库.

任何帮助将非常感激!

script您的executeClientScript操作的属性看起来像是在计算.源应该看起来像这样:

<xp:executeClientScript>
    <xp:this.script>
        <![CDATA[if(XSP.getElementById("#{id:ProjectTitle}").value == ""){...
]]></xp:this.script>
</xp:executeClientScript>

相反,你有这个:

<xp:executeClientScript>
    <xp:this.script>
        <![CDATA[#{javascript:if(XSP.getElementById("#{id:ProjectTitle}").value == ""){...
}]]></xp:this.script>
</xp:executeClientScript>

该语法意味着,您不是简单地输入客户端JavaScript来执行,而是运行服务器端JavaScript来计算客户端JavaScript应该是什么.服务器端JavaScript没有XSP像客户端JavaScript那样定义全局对象,这就是为什么你会得到一个ReferenceError.

#{javascript:从CDATA块的开头删除,最后}从结尾删除,代码将在您想要的上下文中执行.
