EasyUI的doCellTip实现鼠标放到单元格上提示单元格内容

//扩展$.extend($.fn.datagrid.methods, { /** * 开打提示功能 * @param {} jq * @param {} params 提示消息框的样式 * @return {} */ doCellTip : function(jq, params) { function showTip(data, td, e) { if ($(td).text() == "") return; data.tooltip.text($(td).text()).css({ top : (e.pageY + 10) + 'px', left : (e.pageX + 20) + 'px', 'z-index' : $.fn.window.defaults.zIndex, display : 'block' }); }; return jq.each(function() { var grid = $(this); var options = $(this).data('datagrid'); if (!options.tooltip) { var panel = grid.datagrid('getPanel').panel('panel'); var defaultCls = { 'border' : '1px solid #333', 'padding' : '1px', 'color' : '#333', 'background' : '#f7f5d1', 'position' : 'absolute', 'max-width' : '200px', 'border-radius' : '4px', '-moz-border-radius' : '4px', '-webkit-border-radius' : '4px', 'display' : 'none' } var tooltip = $("<div></div>").appendTo('body'); tooltip.css($.extend({}, defaultCls, params.cls)); options.tooltip = tooltip; panel.find('.datagrid-body').each(function() { var delegateEle = $(this).find('> div.datagrid-body-inner').length ? $(this).find('> div.datagrid-body-inner')[0] : this; $(delegateEle).undelegate('td', 'mouseover').undelegate( 'td', 'mouseout').undelegate('td', 'mousemove') .delegate('td', { 'mouseover' : function(e) { if (params.delay) { if (options.tipDelayTime) clearTimeout(options.tipDelayTime); var that = this; options.tipDelayTime = setTimeout( function() { showTip(options, that, e); }, params.delay); } else { showTip(options, this, e); } }, 'mouseout' : function(e) { if (options.tipDelayTime) clearTimeout(options.tipDelayTime); options.tooltip.css({ 'display' : 'none' }); }, 'mousemove' : function(e) { var that = this; if (options.tipDelayTime) { clearTimeout(options.tipDelayTime); options.tipDelayTime = setTimeout( function() { showTip(options, that, e); }, params.delay); } else { showTip(options, that, e); } } }); }); } }); }, /** * 关闭消息提示功能 * @param {} jq * @return {} */ cancelCellTip : function(jq) { return jq.each(function() { var data = $(this).data('datagrid'); if (data.tooltip) { data.tooltip.remove(); data.tooltip = null; var panel = $(this).datagrid('getPanel').panel('panel'); panel.find('.datagrid-body').undelegate('td', 'mouseover').undelegate('td', 'mouseout') .undelegate('td', 'mousemove') } if (data.tipDelayTime) { clearTimeout(data.tipDelayTime); data.tipDelayTime = null; } }); } });
