EasyUI DataGrid 相同连续列合并

$.extend($.fn.datagrid.methods, {
autoMergeCells: function(jq, fields) {
return jq.each(function() {
var target = $(this);
if (!fields) {
fields = target.datagrid("getColumnFields");
}
var rows = target.datagrid("getRows");
var i = 0,
j = 0,
temp = {};
for (i; i < rows.length; i++) {
var row = rows[i];
j = 0;
for (j; j < fields.length; j++) {
var field = fields[j];
var tf = temp[field];
if (!tf) {
tf = temp[field] = {};
tf[row[field]] = [i];
} else {
var tfv = tf[row[field]];
if (tfv) {
tfv.push(i);
} else {
tfv = tf[row[field]] = [i];
}
}
}
}
$.each(temp,
function(field, colunm) {
$.each(colunm,
function() {
var group = this;

if (group.length > 1) {
var before, after, megerIndex = group[0];
for (var i = 0; i < group.length; i++) {
before = group[i];
after = group[i + 1];
if (after && (after - before) == 1) {
continue;
}
var rowspan = before - megerIndex + 1;
if (rowspan > 1) {
target.datagrid('mergeCells', {
index: megerIndex,
field: field,
rowspan: rowspan
});
}
if (after && (after - before) != 1) {
megerIndex = after;
}
}
}
});
});
});
}
});

使用方法

$('#dg').datagrid({
url: 'datagrid_data.json',
onLoadSuccess: function(data) {
//所有列进行合并操作
//$(this).datagrid("autoMergeCells");
//指定列进行合并操作
$(this).datagrid("autoMergeCells", ['groupId', 'commId']);
}
});
