JQGrid定義私はJSONの各行をループしてチェックしてい
をやろうとしている何
$("#myjqgrid").jqGrid({
url: "jqgrid.json",
datatype: "json",
contentType: "application/x-javascript; charset=utf-8",
colNames:['linkimg'],
colModel:[
{name:'linkimg',index:'linkimg', width:100, align:"center", resizable:false}
],
jsonReader: {
root: "mypage.outerwrapper.innerwrapper.rows",
repeatitems: false
},
rowNum:5,
rowList:[5,10,15],
pager: '#Pager',
sortname: 'id',
recordpos: 'left',
multiboxonly:true,
viewrecords: true,
sortorder: "desc",
multiselect: true,
width: "1406",
height: "100%",
scrolloffset: 0,
loadonce: true,
sortable: true,
sorttype: "text"
})
の場合プロパティ。 trueの場合は、に設定されたtext-decorationの行が必要です。
loadComplete: function(data){
var x, rowItem;
for (x = 0; x < data.mypage.outerwrapper.innerwrapper.rows.length; x++) {
rowItem = data.mypage.outerwrapper.innerwrapper.rows[x];
var rowItemRead = rowItem.read;
if(rowItemRead === true){
$("#" + rowItem.id + " > td").css({"text-decoration":"underline"});
}
}
}
コードの上記部分が作動しているが、問題は
Iは、ページ1からページ2 OR 2ページから3ページに移動すると、私はエラーメッセージ
を得ることですmypage.outerwrapper
はnullまたはオブジェクトではありません。 （jsonReaderとloadComplete付き）
全JQGrid定義コード
