我看了所有Q&关于在jqGrid的过滤器工具栏中使用Multiselect小部件。我注意到在几乎所有的解决方案中,jqGrid版本和jquery版本都不是当前版本。我正在使用jqGrid(4.13.4)和jquery(3.1.1)以及jqueryUI(1.12.1)的最新版本。
我在javascript中尝试了here中的示例代码。它加载正常,但是当我尝试从多选中选择任何值时,即使取消选择多选中的值,网格也会清除并保持清除状态。
我只想确保此解决方案适用于我正在使用的最新版本的free-jqGrid,jquery和jqueryUI。

我在the old answer的免费jqGrid中发布了一个使用Multiselect小部件的示例。免费jqGrid的更高版本支持"in"
操作,这在使用Multiselect小部件时非常实用。
我为你创建了the new demo,如下图所示。
它从testJsonData.json加载输入数据,找到ship_via
内beforeProcessing
列的所有唯一值,并根据值设置searchoptions.value
。该演示使用来自GitHub的免费jqGrid的最新代码(它最近为4.13.4)。我打算很快将GitHub中的代码发布为4.13.5或4.14.0。该演示使用Eric Hyndse创建的Multiselect widget的当前v1.17版本。演示代码是
var getUniqueNames = function (columnName, mydata) {
var texts = $.map(mydata, function (item) {
return item[columnName];
}),
uniqueTexts = [], textsLength = texts.length, text, textsMap = {}, i;
for (i = 0; i < textsLength; i++) {
text = texts[i];
if (text !== undefined && textsMap[text] === undefined) {
// to test whether the texts is unique we place it in the map.
textsMap[text] = true;
uniqueTexts.push(text);
}
}
return uniqueTexts;
},
buildSearchSelect = function (uniqueNames) {
var values = "";
$.each(uniqueNames, function () {
values += this + ":" + this + ";";
});
return values.slice(0, -1);
},
initMultiselect = function (searchOptions) {
var $elem = $(searchOptions.elem),
options = {
selectedList: 2,
height: "auto",
checkAllText: "all",
uncheckAllText: "no",
noneSelectedText: "Any",
open: function () {
var $menu = $(".ui-multiselect-menu:visible");
$menu.addClass("ui-jqdialog").width("auto");
$menu.find(">ul").css("maxHeight", "200px");
}
};
if (searchOptions.mode === "filter") {
options.minWidth = "auto";
}
$elem.multiselect(options);
$elem.siblings("button.ui-multiselect").css({
width: "100%",
margin: "1px 0",
paddingTop: ".3em",
paddingBottom: "0"
});
},
setSearchSelect = function (columnName, data) {
var values = buildSearchSelect(getUniqueNames.call(this, columnName, data));
$(this).jqGrid("setColProp", columnName, {
stype: "select",
searchoptions: {
value: values,
sopt: ["in"],
attr: {
multiple: "multiple",
size: 4
},
selectFilled: initMultiselect
}
});
},
myDefaultSearch = "cn",
beforeProcessingHandler1 = function (data) {
var $this = $(this), p = $this.jqGrid("getGridParam");
// !!! it will be called only after loading from the server
// datatype is always "json" here
setSearchSelect.call(this, "ship_via", data);
if (this.ftoolbar === true) {
// if the filter toolbar is not already created
$("#gs_" + this.id + "ship_via").multiselect("destroy");
$this.jqGrid('destroyFilterToolbar');
}
if (p.postData.filters) {
p.search = true;
}
$this.jqGrid("filterToolbar", {
//stringResult: true,
defaultSearch: myDefaultSearch,
beforeClear: function () {
$(this.grid.hDiv)
.find(".ui-search-toolbar button.ui-multiselect")
.each(function () {
$(this).prev("select[multiple]").multiselect("refresh");
});
}
});
};
$("#list").jqGrid({
url: "testJsonData.json",
datatype: "json",
colNames: ["Client", "Amount", "Tax", "Total", "Shipped via", "Notes"],
colModel: [
{ name: "name", width: 65 },
{ name: "amount", width: 75, template: "number" },
{ name: "tax", width: 52, template: "number" },
{ name: "total", width: 65, template: "number" },
{ name: "ship_via", width: 85, align: "center" },
{ name: "note", width: 100, sortable: false }
],
rowNum: 5,
sortname: "name",
iconSet: "fontAwesome",
autoencode: true,
loadonce: true,
forceClientSorting: true, // local sorting and filtering data loaded from the server
beforeProcessing: beforeProcessingHandler1,
rowList: [5, 10, 20, 30, 100],
pager: true,
pagerRightWidth: 120, // fix wrapping or right part of the pager
viewrecords: true,
sortable: true
}).jqGrid("navGrid", { add: false, edit: false, del: false, search: false });

以下是下拉列表中“任意”选项的修复,以返回选择控件中的所有选项。
修改代码的这一部分:
modifySearchingFilter = function (separator) {
var i, l, rules, rule, parts, j, group, str,
filters = $.parseJSON(this.p.postData.filters);
console.log(filters);
rules = filters.rules;
console.log(rules.length)
for (i = 0; i < rules.length; i++) {
rule = rules[i];
if (rule.data == "") {
rule.op = "ne"; //this will return anything not equal to ""
}
}
console.log("after splicing: " + JSON.stringify(filters))
this.p.postData.filters = JSON.stringify(filters);},
重要的部分是添加规则的检查并为操作员返回不相等(“ne”)。这将创建一个规则,过滤掉所有不等于空字符串的选项。这应该返回所有选择选项,换句话说,将select重置为初始状态,显示select中的所有选项,它将返回网格中的所有记录。希望这有助于将来。
