jQGrid列选择器模态叠加
看一下这个例子 ，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按钮会显示一个模态forms，但后面没有叠加。
我的问题是：如何在我的Column Chooser弹出窗口后面显示黑色叠加层？
columnChooser目前没有未记录的选项 ：
$(this).jqGrid('columnChooser', {modal: true}); 该演示certificate了这一点。 也可以为$.jgrid.col设置columnChooser默认参数：
$.extend(true, $.jgrid.col, { modal: true });
最近我发布了扩展columnChooser的一些function的columnChooser ，但只有部分更改是jqGrid的当前代码。 尽管如此，在新版本中可以设置更多关于新的dialog_opts选项的jQuery UI Dialog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function，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 = $(''); 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 passed the string "destroy"). */ "msel" : "multiselect", /* "msel_opts" : {}, */ /* dlog is either the name of a ui widget class that behaves in a dialog-like way, or a function, that supports creating a dialog (when passed dlog_opts) or destroying a dialog (when passed the string "destroy") */ "dlog" : "dialog", /* dlog_opts is either an option object to be passed to "dlog", or (more likely) a function that creates the options object. The default produces a suitable options object for ui.dialog */ "dlog_opts" : function(opts) { var buttons = {}; buttons[opts.bSubmit] = function() { opts.apply_perm(); opts.cleanup(false); }; buttons[opts.bCancel] = function() { opts.cleanup(true); }; return $.extend(true, { "buttons": buttons, "close": function() { opts.cleanup(true); }, "modal" : opts.modal ? opts.modal : false, "resizable": opts.resizable ? opts.resizable : true, "width": opts.width+20, resize: function (e, ui) { var $container = $(this).find('>div>div.ui-multiselect'), containerWidth = $container.width(), containerHeight = $container.height(), $selectedContainer = $container.find('>div.selected'), $availableContainer = $container.find('>div.available'), $selectedActions = $selectedContainer.find('>div.actions'), $availableActions = $availableContainer.find('>div.actions'), $selectedList = $selectedContainer.find('>ul.connected-list'), $availableList = $availableContainer.find('>ul.connected-list'), dividerLocation = opts.msel_opts.dividerLocation || $.ui.multiselect.defaults.dividerLocation; $container.width(containerWidth); // to fix width like 398.96px $availableContainer.width(Math.floor(containerWidth*(1-dividerLocation))); $selectedContainer.width(containerWidth - $availableContainer.outerWidth() - ($.browser.webkit ? 1: 0)); $availableContainer.height(containerHeight); $selectedContainer.height(containerHeight); $selectedList.height(Math.max(containerHeight-$selectedActions.outerHeight()-1,1)); $availableList.height(Math.max(containerHeight-$availableActions.outerHeight()-1,1)); } }, opts.dialog_opts || {}); }, /* Function to get the permutation array, and pass it to the "done" function */ "apply_perm" : function() { $('option',select).each(function(i) { if (this.selected) { self.jqGrid("showCol", colModel[this.value].name); } else { self.jqGrid("hideCol", colModel[this.value].name); } }); var perm = []; //fixedCols.slice(0); $('option:selected',select).each(function() { perm.push(parseInt(this.value,10)); }); $.each(perm, function() { delete colMap[colModel[parseInt(this,10)].name]; }); $.each(colMap, function() { var ti = parseInt(this,10); perm = insert(perm,ti,ti); }); if (opts.done) { opts.done.call(self, perm); } }, /* Function to cleanup the dialog, and select. Also calls the done function with no permutation (to indicate that the columnChooser was aborted */ "cleanup" : function(calldone) { call(opts.dlog, selector, 'destroy'); call(opts.msel, select, 'destroy'); selector.remove(); if (calldone && opts.done) { opts.done.call(self); } }, "msel_opts" : {} }, $.jgrid.col, opts || {}); if($.ui) { if ($.ui.multiselect ) { if(opts.msel == "multiselect") { if(!$.jgrid._multiselect) { // should be in language file alert("Multiselect plugin loaded after jqGrid. Please load the plugin before the jqGrid!"); return; } opts.msel_opts = $.extend($.ui.multiselect.defaults,opts.msel_opts); } } } if (opts.caption) { selector.attr("title", opts.caption); } if (opts.classname) { selector.addClass(opts.classname); select.addClass(opts.classname); } if (opts.width) { $(">div",selector).css({"width": opts.width,"margin":"0 auto"}); select.css("width", opts.width); } if (opts.height) { $(">div",selector).css("height", opts.height); select.css("height", opts.height - 10); } var colModel = self.jqGrid("getGridParam", "colModel"); var colNames = self.jqGrid("getGridParam", "colNames"); var colMap = {}, fixedCols = []; select.empty(); $.each(colModel, function(i) { colMap[this.name] = i; if (this.hidedlg) { if (!this.hidden) { fixedCols.push(i); } return; } select.append(""); }); function call(fn, obj) { if (!fn) { return; } if (typeof fn == 'string') { if ($.fn[fn]) { $.fn[fn].apply(obj, $.makeArray(arguments).slice(2)); } } else if ($.isFunction(fn)) { fn.apply(obj, $.makeArray(arguments).slice(2)); } } var dopts = $.isFunction(opts.dlog_opts) ? opts.dlog_opts.call(self, opts) : opts.dlog_opts; call(opts.dlog, selector, dopts); var mopts = $.isFunction(opts.msel_opts) ? opts.msel_opts.call(self, opts) : opts.msel_opts; call(opts.msel, select, mopts); // fix height of elements of the multiselect widget var resizeSel = "#colchooser_"+$.jgrid.jqID(self[0].p.id), $container = $(resizeSel + '>div>div.ui-multiselect'), $selectedContainer = $(resizeSel + '>div>div.ui-multiselect>div.selected'), $availableContainer = $(resizeSel + '>div>div.ui-multiselect>div.available'), containerHeight, $selectedActions = $selectedContainer.find('>div.actions'), $availableActions = $availableContainer.find('>div.actions'), $selectedList = $selectedContainer.find('>ul.connected-list'), $availableList = $availableContainer.find('>ul.connected-list'); $container.height($container.parent().height()); // increase the container height containerHeight = $container.height(); $selectedContainer.height(containerHeight); $availableContainer.height(containerHeight); $selectedList.height(Math.max(containerHeight-$selectedActions.outerHeight()-1,1)); $availableList.height(Math.max(containerHeight-$availableActions.outerHeight()-1,1)); // extend the list of components which will be also-resized selector.data('dialog').uiDialog.resizable("option", "alsoResize", resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect'); } });
在这种情况下，您可以继续使用jquery.jqGrid.min.js的原始最小化版本，并且使用的代码可以只是$(this).jqGrid('columnChooser'); 。 与所有默认设置一起，它将是
$.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'); } });
该演示演示了该方法。 这些变化的主要优势 – 真正可resize的列选择器：
更新： jqGrid的免费jqGrid fork，我从2014年底开始开发，包含导致columnChooser的修改代码。
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.
该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。
刚看过代码，试着添加这一行：
jqModal : true,
这段代码：
$grid.jqGrid('navButtonAdd', '#pager', { caption: "", buttonicon: "ui-icon-calculator", title: "Choose columns", onClickButton: function () { ....
像这样：
$grid.jqGrid('navButtonAdd', '#pager', { caption: "", buttonicon: "ui-icon-calculator", title: "Choose columns", jqModal : true, onClickButton: function () { ....
