jQGrid列选择器模态叠加
关注这个example，请注意点击“搜索”按钮会如何显示一个模态表单，背后有一个黑暗的叠加层。现在注意点击Column Chooser按钮会如何显示模态表单，但后面没有叠加。
我的问题是：如何让黑色叠加显示在我的Column Chooser弹出窗口后面？

目前option
中没有文档columnChooser$(this).jqGrid('columnChooser', {modal: true});
The demo证明了这一点。也可以针对columnChooser设置$.jgrid.col的默认参数：
$.extend(true, $.jgrid.col, {
modal: true
});
最近我发布了the suggestion来扩展columnChooser的一些功能，但只有a part更改是jqGrid的当前代码。然而，在新版本中，可以针对新的dialog_opts选项设置更多jQuery UI Dialog个选项。例如，可以使用以下内容
$(this).jqGrid('columnChooser', {
dialog_opts: {
modal: true,
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
要使用我建议的完整功能，您可以覆盖columnChooser的标准实现。可以通过包含以下代码来实现此目的
$.jgrid.extend({
columnChooser : function(opts) {
var self = this;
if($("#colchooser_"+$.jgrid.jqID(self[0].p.id)).length ) { return; }
var selector = $('<div id="colchooser_'+self[0].p.id+'" style="position:relative;overflow:hidden"><div><select multiple="multiple"></select></div></div>');
var select = $('select', selector);
function insert(perm,i,v) {
if(i>=0){
var a = perm.slice();
var b = a.splice(i,Math.max(perm.length-i,i));
if(i>perm.length) { i = perm.length; }
a[i] = v;
return a.concat(b);
}
}
opts = $.extend({
"width" : 420,
"height" : 240,
"classname" : null,
"done" : function(perm) { if (perm) { self.jqGrid("remapColumns", perm, true); } },
/* msel is either the name of a ui widget class that
extends a multiselect, or a function that supports
creating a multiselect object (with no argument,
or when passed an object), and destroying it (when

"msel" : "multiselect",
/* "msel_opts" : {}, */
/* dlog is either the name of a ui widget class that

return $.extend(true, {

selector.data('dialog').uiDialog.resizable("option", "alsoResize",
resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect');
}
});
如果您可以继续使用jquery.jqGrid.min.js的原始最小化版本，则使用的代码可以只是$(this).jqGrid('columnChooser');。与所有默认设置一起，它将像
$.extend(true, $.ui.multiselect, {
locale: {
addAll: 'Make all visible',
removeAll: 'Hidde All',
itemsCount: 'Avlialble Columns'
}
});
$.extend(true, $.jgrid.col, {
width: 450,
modal: true,
msel_opts: {dividerLocation: 0.5},
dialog_opts: {
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
$(this).jqGrid('columnChooser');
}
});
The demo演示了这种方法。这些变化的主要优势 - 真正可调整大小的列选择器：
更新： Free jqGrid jqGrid的分支，我从2014年底开始开发，包含因columnChooser修改后的代码。
答案 1 :(得分：2)
在移动设备上尝试代码时出现以下错误。
Result of expression 'selector.data('dialog').uiDialog' [undefined] is not an object.
错误指向以下代码行。
selector.data('dialog').uiDialog.resizable("option", "alsoResize", resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect');
当我检查代码时，我发现数据对象没有任何名为uiDialog的东西。

只是通过代码查看，尝试添加以下行：
jqModal : true,
到此代码：
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
....
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
jqModal : true,
onClickButton: function () {
....
