datagrid 动态合并行

easyui datagrid 需要动态合并行，可以考虑在加载完数据之后按照文本合并

$('#datagrid').datagrid({
method:"post",
loadMsg:'数据加载中请稍后……',
pagination:false,
rownumbers:false,
resizable:true,
fitColumns:true,
nowrap:true,
singleSelect:true,
striped : true,
data:data,
columns:[[
// ...
]],
onLoadSuccess:function (data){
console.log(data);
if(data.rows.length>0){
mergeCell("datagrid","colName1,colName2");
}
}
});
}

加载之后对传入的列 动态合并

function mergeCell(dgId,fields){
var fieldArray=fields.split(",");
var dg=$('#' + dgId);
var rowCount=dg.datagrid("getRows").length;
for (var i = 0; i < fieldArray.length; i++) {
var begin=0;
var length=0;
var perTxt="";
var curTxt="";
var field = fieldArray[i];
for (var j = 0; j < rowCount; j++) {
curTxt=dg.datagrid("getRows")[j][field];
if (curTxt==perTxt) {
length++;
}else if(length==0){
begin++;
}
if ((curTxt!=perTxt&&length!=0)||(curTxt==perTxt&&j==rowCount-1)) {
dg.datagrid("mergeCells",{
index: begin-1,
field: field,
rowspan: length+1,
colspan: null
});
begin+=(length+1);
length=0;
}
perTxt=curTxt;
}
}
}

后面发现下面情况子列会跨父列合并：

希望不要合并 5，修改代码如下：

function mergeCell(dgId,fields){
var fieldArray=fields.split(",");
var dg=$('#' + dgId);
var rowCount=dg.datagrid("getRows").length;
for (var i = 0; i < fieldArray.length; i++) {
var begin=0;
var length=0;
var perTxt="";
var curTxt="";
var field = fieldArray[i];
for (var j = 0; j < rowCount; j++) {
curTxt="";
for (var k = 0; k <= i; k++) {
curTxt+=dg.datagrid("getRows")[j][fieldArray[k]];
}
if (curTxt==perTxt) {
length++;
}else if(length==0){
begin++;
}
if ((curTxt!=perTxt&&length!=0)||(curTxt==perTxt&&j==rowCount-1)) {
dg.datagrid("mergeCells",{
index: begin-1,
field: field,
rowspan: length+1,
colspan: null
});
begin+=(length+1);
length=0;
}
perTxt=curTxt;
}
}
}
