ExtJs 4: How To Add Grid Cell Tooltip
最近忙一个项目的时候需要实现鼠标移到grid的某一行上提示消息。花了半天时间才解决。在网上找很久终于有找到一个有用的。我的版本是extjs4.
效果如图
Ext.onReady(function () { // Init the singleton. Any tag-based quick tips will start working. Ext.tip.QuickTipManager.init(); Ext.widget('grid', { title: 'Users', store: { fields: ['name', 'email', 'comment'], data: [ { 'name': 'Lisa', 'email': 'lisa@simpsons.com', 'comment': 'some comment' }, { 'name': 'Bart', 'email': 'bart@simpsons.com', 'comment': 'comment' }, { 'name': 'Homer', 'email': 'home@simpsons.com', 'comment': 'some very long comment' }, { 'name': 'Marge', 'email': 'marge@simpsons.com', 'comment': 'some very very very very long comment' } ] }, columns: [ { header: 'Name', dataIndex: 'name', width: 100 }, { header: 'Email', dataIndex: 'email', width: 150 }, { header: 'comment', dataIndex: 'comment', flex: 1, renderer: function (value, meta, record) { var max = 15; meta.tdAttr = 'data-qtip="' + value + '"'; return value.length < max ? value : value.substring(0, max - 3) + '...'; } } ], width: 400, renderTo: 'output' }); });
