我对jQgrid有一些乐趣,但现在我需要实现一些我称之为“高级”的东西,因为我甚至不知道这是否是无意义的,或者是否无法完成但是我们去了
让我们在具有SELECT
元素的页面中进行思考,该元素稍后将变为Select2JS,并且还将使用将用于执行搜索的普通INPUT
元素。见下图(INPUT尚未显示,因为这是WIP)。
该页面还包含一个网格(jQgrid),如上图所示。我想:
我认为(2)和(3)可以使用here描述的方法完成 - 如果我错了,请纠正我 - 但是(1)呢?如何避免网格为完成数据而进行的初始AJAX调用?
这是网格定义:
var manage_form_listing_grid = $("#manage_form_listing");
$(window).on("resize", maximizeGrid(manage_form_listing_grid));
manage_form_listing_grid.jqGrid({
colNames: ["Actions", "Form Name", "Fax Number", "FileName", "Folder"],

答案 0 :(得分:1)
我认为您在制作过程中应该在网格中使用datatype: "local"
而不是datatype: "json"
。选项datatype: "local"
将阻止Ajax请求并忽略url
选项。另一方面,在Select2元素的select事件或事件处理程序$(document).on("click", $load_form, ...
内部,您应该再添加一行重置为datatype
到"json"
的行。例如,the old answer中的代码可以修改为
$(document).on("click", $load_form, function (ev) {
var p = $questions_grid.jqGrid("getGridParam");
p.datatype = "json"; // !!! the new line
p.url = "/ajax/questions/get/" + $("#load_form").data("formid");
$questions_grid.trigger("reloadGrid");
});
