Question

ext中file控件的浏览按钮的样式 怎样改变？？

Answer 1

修改一下代码
this.input_file.on("change", function(e) {
if (navigator.userAgent.indexOf('Firefox') >= 0) { //Firefox浏览器
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
} catch (e) {
alert('Unable to access local files due to browser security settings. To overcome this, follow these steps: (1) Enter "about:config" in the URL field; (2) Right click and select New->Boolean; (3) Enter "signed.applets.codebase_principal_support" (without the quotes) as a new preference name; (4) Click OK and try loading the file again.');
}
} else if(Ext.isIE){
this.input_file.dom.select();
url = document.selection.createRange().text;
}
var url = url || this.input_file.dom.value;
panel.getForm().findField('fileValue').setValue(url);
}, this);

访问firefox about:config 添加 signed.applets.codebase_principal_support 属性 值为true
