extJS 现在依然存在很多bug,有时挺烦人的。比如,最近就需要复制表格信息,extjs的grid却不支持,研究半天,覆盖了css,但只在非ie的浏览器有效。修改了extjs源码才解决了在ie的问题。
1、添加以下css代码:
<style type="text/css">
.x-grid-row
{
line-height:13px;vertical-align:top;padding:0 1px; -moz-user-select:text!important;-khtml-user-select:text!important;-webkit-user-select:text!important;
}
.x-grid-cell
{
overflow:hidden;font:normal 13px tahoma, arial, verdana, sans-serif;-moz-user-select:text!important;-khtml-user-select:text!important;-webkit-user-select:text!important;
}
.x-unselectable
{
-moz-user-select:text!important;-khtml-user-select:text!important;-webkit-user-select:text!important;
}
</style>
2、修改extjs4.0的ext-all.js(或ext-all-debug.js)三处代码:
找到 Ext.override(Ext.core.Element, {
....
unselectable : function(){
var me = this;
me.dom.unselectable = "on";//1、把me.dom.unselectable = "on"修改为me.dom.unselectable = ""
me.swallowEvent("selectstart", true);//2、把ture改成false
me.applyStyles("-moz-user-select:none;-khtml-user-select:none;");
me.addCls(Ext.baseCSSPrefix + 'unselectable');
return me;
}
...
});
找到 Ext.override(Ext.view.TableChunker, {
...
metaRowTpl: [
'<tr class="' + Ext.baseCSSPrefix + 'grid-row {addlSelector} {[this.embedRowCls()]}" {[this.embedRowAttr()]}>',
'<tpl for="columns">',
'<td class="{cls} ' + Ext.baseCSSPrefix + 'grid-cell ' + Ext.baseCSSPrefix + 'grid-cell-{columnId} {{id}-modified} {{id}-tdCls} {[this.firstOrLastCls(xindex, xcount)]}" {{id}-tdAttr}><div unselectable="on" //3、把此处的unselectable="on"改成unselectable="" class="' + Ext.baseCSSPrefix + 'grid-cell-inner ' + Ext.baseCSSPrefix + 'unselectable" style="{{id}-style}; text-align: {align};">{{id}}</div></td>',
'</tpl>',
'</tr>'
]
...
});
