我尝试使用jsonreader读取数据，将数据类型设置为“json”，将root设置为“results”。
jqgrid中没有填充数据，有人教育我，我在这里缺少什么？
答案 0 :(得分：1)
您的代码中存在错误，因为对jqGrid选项的含义存在很小的误解。如果您在代码中定义了myStr之类的变量
var myStr = {
"version" : 2,
...
"results" : [
{
...
}
]
};
你不使用JSON 。它只是使用对象文字来创建新对象。这种语法是在JavaScript中创建和初始化对象的最简单有效的方法。只有属性具有特殊字符时，才需要在"或'中包含属性名称。所以相同的代码可以重写为
var myStr = {
version : 2,
...
results : [
{
...
}
]
};
所以我想强调一下，上面根本不使用JSON。 datatype参数（不是dataType）的正确值应为"local"而不是"json"。在这种情况下，将忽略选项jsonReader或loadonce。输入数据应该是由jqGrid的data选项指定的项目数组。
因此固定代码应如下所示
$("#myGrid").jqGrid({
datatype: "local",
data: myStr.results,
colNames: ["Trending Jobs"],
colModel: [
{ name: "url" }
],
rowNum: 5,
rowList: [5, 10, 20, 100, 10000],
pager: "#pager",
gridview: true,
rownumbers: true,
viewrecords: true,
height: "auto"
});
（见the demo）。
如果您的实际代码确实从服务器加载数据，则应使用url参数。如果可以使用选项jsonReader或loadonce，代码如下所示
$("#myGrid").jqGrid({
url: "Sri2.json",
datatype: "json",
jsonReader: {
repeatitems: false,
root: "results"
},
loadonce: true,
colNames: ["Trending Jobs"],
colModel: [
{ name: "url" }
],
rowNum: 5,
rowList: [5, 10, 20, 100, 10000],
pager: "#pager",
gridview: true,
rownumbers: true,
viewrecords: true,
height: "auto"
});
（见another demo）。
您的代码具有奇怪的属性，例如onmousedown。如果您需要在某个单元格上设置onmousedown属性，则可以在cellattr中使用colModel属性。它允许您将任何附加属性设置为<td>元素，该元素代表网格的单元格。例如，one more demo使用以下代码
function indeed_clk (obj, id) {
alert("onmousedown with id=" + id);
}
$(function () {
var myStr = {
...
"results" : [
{
...
"onmousedown" : "indeed_clk(this, '1050');",
...
}
]
};
$("#myGrid").jqGrid({
datatype: "local",
data: myStr.results,
colNames: ["Trending Jobs"],
colModel: [
{
name: "url",
title: false,
cellattr: function (rowId, cellValue, rawObject) {
if (rawObject.onmousedown) {
return 'onmousedown="' + rawObject.onmousedown + '"';
}
}
}
],
rowNum: 5,
rowList: [5, 10, 20, 100, 10000],
pager: "#pager",
gridview: true,
rownumbers: true,
viewrecords: true,
height: "auto"
});
});
设置onmousedown属性，该属性调用全局函数indeed_clk。将使用onmousedown属性在url列中的单元格上设置cellattr。
