感谢this回答我能得到JavaScript的时候通过ExtJS的AJAX调用加载执行。

但是，下面的code没有在所有浏览器相同的（在Mac上）：

镀铬：作品，警报弹出 在野生动物园：作品，警报弹出 在Firefox中：作品的但只有当萤火虫启用的，当萤火虫未启用，该脚本将被忽略

如何获得的JavaScript在Firefox中通过AJAX调用来执行，而无需安装萤火虫？

  Ext.onReady（函数（）{

    VAR menuItemStart =新Ext.Panel（{
        ID：panelStart，
        标题：开始，
        HTML：这是启动菜单项。，
        CLS：'菜单项
    }）;

    VAR menuItemApplication =新Ext.Panel（{
        ID：panelApplication，
        标题：应用程序，
        HTML：这是申请页面，
        CLS：'菜单项
    }）;

    VAR regionMenu =新Ext.Panel（{
        区域：西方，
        驳：真，
        宽度：210，
        布局：手风琴，
        layoutConfig：{
            动画：真
        }，
        项目：[menuItemStart，menuItemApplication]
    }）;

    VAR regionContent =新Ext.Panel（{
        编号：'含量 - 面积，
        区域：中心，
        填充：'10'，
        自动滚屏：真正的，
        HTML：'这是内容的
    }）;

    新Ext.Viewport（{
        布局：边境，
        项目：[regionMenu，regionContent]
    }）;

    menuItemStart.header.on（'点击'，函数（）{
        Ext.Ajax.request（{
            网址：内容/ view_start.php'，
            成功：函数（objServerResponse）{
                regionContent.update（objServerResponse.responseText）;
            }
        }）;
    }）;

    menuItemApplication.header.on（'点击'，函数（）{
        Ext.Ajax.request（{
            网址：内容/ view_application.php'，
            成功：函数（objServerResponse）{
                VAR的responseText = objServerResponse.responseText;
                执行console.log（responseText的）;
                regionContent.update（responseText的）;
                VAR脚本，scriptsFinder = /＆LT;脚本[^＆GT;] *＆GT;（[\ S \ S] +）＆LT; \ / SCRIPT＆GT; / GI;
                而（脚本= scriptsFinder.exec（responseText的））{
                    的eval（脚本[1]）;
                }
            }
        }）;

    }）;
}）;
 

这是正装的基础：

 ＆LT;脚本类型=文/ JavaScript的＆GT;
    警报（内部应用程序视图'）;
＆LT; / SCRIPT＆GT;
＆LT; PHP
回声这是在应用程序视图。日期（Y-M-D H：我：S'）;
？＆GT;
 

解决方案

的console.log 是罪魁祸首。

每当你登录的JavaScript，这是一个好主意，以检查是否控制台调用它的函数之前存在的：

 如果（window.console）的console.log（'不管'）;
 

这样的话，它只会在控制台可以执行。

Thanks to this answer I was able to get javascript to execute when being loaded via an ExtJS AJAX call.

However, the following code does not work the same in all browsers (on mac):

chrome: works, alert pops up safari: works, alert pops up firefox: works, but only when Firebug is enabled, when Firebug is not enabled, the script is ignored

How can I get javascript to execute via AJAX call in Firefox without having Firebug installed?

Ext.onReady(function(){

    var menuItemStart = new Ext.Panel({
        id: 'panelStart',
        title: 'Start',
        html: 'This is the start menu item.',
        cls:'menuItem'
    });

    var menuItemApplication = new Ext.Panel({
        id: 'panelApplication',
        title: 'Application',
        html: 'this is the application page',
        cls:'menuItem'
    });

    var regionMenu = new Ext.Panel({
        region:'west',
        split:true,
        width: 210,
        layout:'accordion',
        layoutConfig:{
            animate:true
        },
        items: [ menuItemStart, menuItemApplication ]
    });

    var regionContent = new Ext.Panel({
        id: 'contentArea',
        region: 'center',
        padding:'10',
        autoScroll: true,
        html: 'this is the content'
    });

    new Ext.Viewport({
        layout: 'border',
        items: [ regionMenu, regionContent ]
    });

    menuItemStart.header.on('click', function() {
        Ext.Ajax.request({
            url: 'content/view_start.php',
            success: function(objServerResponse) {
                regionContent.update(objServerResponse.responseText);
            }
        });
    });

    menuItemApplication.header.on('click', function() {             
        Ext.Ajax.request({
            url: 'content/view_application.php',
            success: function(objServerResponse) {
                var responseText = objServerResponse.responseText;
                console.log(responseText);
                regionContent.update(responseText);
                var scripts, scriptsFinder=/<script[^>]*>([\s\S]+)<\/script>/gi;
                while(scripts=scriptsFinder.exec(responseText)) {
                    eval(scripts[1]);
                }
            }
        });

    });
});

The base that is being loaded:

<script type="text/javascript">
    alert('inside application view');
</script>
<?php
echo 'this is the application view at ' . date('Y-m-d h:i:s');
?>

解决方案

console.log is your culprit.

Whenever you're logging in JavaScript, it's a good idea to check if console exists before calling it's functions:

if(window.console) console.log('whatever');

That way, it will only execute when the console is available.
