1.Ext 布局出现滚动条

var viewPanel = new Ext.Panel({
???border : false,
???layout: 'fit',
???renderTo: 'mydiv',
???autoScroll : true,
???bodyStyle: 'overflow-x:hidden;',//?隐藏横向滚动条,纵向的overflow-y:hidden;
???items : [feedbackform],
???buttons : [feedbackOK,feedbackCancel],
???plugins: [new Ext.ux.plugins.FitToParent()]
??});

2. js 数组中的简单操作

var array [];

array.push(1);

array.push(2);

a.??? join 数组数据转换字符串

var str = array.join(',');? //1,2

b.??? spice 数组中删除某一个

?

function removeKey(value){
?for(var i = 0; i < array.length; i++) {
??if(array[i] === value){
???array.splice(i,1); //splice(start, delCount, val1,val2,...)1、从哪开始，2、删除count，3.并从该位置起插入val1，val2...n

??}
?}
}
