如何在免费 jqgrid 中的表单和行编辑中使用本机日期选择器
浏览器本机日期选择器用于内联行编辑，如 jqGrid中日期列如何使用input type='date'
Browser native datepicker is used for inline row editing as described in How to use input type='date' for date column in jqGrid
如何使用它来编辑表单呢?我尝试了以下代码:
How to use it for form editing also? I tried code below:
- 网格中的选定行
- 按下工具栏中的编辑按钮
- 在编辑表单中按下保存按钮
在该日期从网格 invdate 列中消失之后.在编辑表单中按下下一个和上一个记录按钮也会导致 invdate 消失.
After that date disappears from grid invdate column. Also pressing next and previous record buttons in edit form cause invdate to disappear.
如果浏览器支持，如何使用浏览器原生 html5 日期类型选择器在编辑表单中编辑和显示日期?
How to edit and show date in edit form using browser native html5 date type picker if it is supported in browser ?

推荐答案
myBeforeSaveRow 中使用的解决方法也需要在表单编辑中实现.相反，我更改了免费 jqGrid 的代码，以便您**根本不需要使用 beforeSaveRow: myBeforeSaveRow.我调整了内联编辑和表单编辑的代码，使其在保存 <input type="date"> 中的数据时可以正常工作.如果不支持 type="date"，则应小心并将 type 的值设置为 text.
The workaround used in myBeforeSaveRow need be implemented in form editing too. Instead of that I changed the code of free jqGrid so that you **don't need to use beforeSaveRow: myBeforeSaveRow at all. I adjusted the code of inline editing and form editing so that it works correctly on saving the data from <input type="date">. One should be only careful and set the value of type to text if type="date" is not supported.
演示使用当前免费jqGrid的代码来自GitHub.我在支持 <input type="date"> 的 Chrome 41、Opera 28 中测试了演示.我测试了 Safari 5.1.7、Firefox 37 和 IE 10 中的更改.演示在这里也可以工作.它使用initDateEdit的以下修改代码:
The demo uses the current code of free jqGrid from GitHub. I tested the demo in Chrome 41, Opera 28 where <input type="date"> is supported. I tested the changes in Safari 5.1.7, Firefox 37 and IE 10. The demo works here too. It use the following modified code of initDateEdit:
var initDateEdit = function (elem, options) {
// we need get the value before changing the type
var orgValue = $(elem).val(), newformat,
cm = $(this).jqGrid("getColProp", options.name);
$(elem).attr("type", "date");
if ((typeof Modernizr !== "undefined" && !Modernizr.inputtypes.date) || $(elem).prop("type") !== "date") {
$(elem).attr("type", "text"); // !!! important to make saving works correctly
$(elem).css({ width: "8em" }).datepicker({
dateFormat: "mm/dd/yy",
autoSize: true,
changeYear: true,
changeMonth: true,
showButtonPanel: true,
showWeek: true
});
} else {
// convert date to ISO
if (orgValue !== "") {
newformat = cm.formatoptions != null && cm.formatoptions.newformat ?
cm.formatoptions.newformat :
$(this).jqGrid("getGridRes", "formatter.date.newformat");
$(elem).val($.jgrid.parseDate.call(this, newformat, orgValue, "Y-m-d"));
}
$(elem).css({width: "11em"});
}
};
内联和表单编辑的其他代码是标准的:
The other code of inline and form editing is the standard:
...
onSelectRow: function (rowid) {
var $self = $(this),
savedRow = $self.jqGrid("getGridParam", "savedRow");
if (savedRow.length > 0 && savedRow[0].id !== rowid) {
$self.jqGrid("restoreRow", savedRow[0].id);
}
$self.jqGrid("editRow", rowid);
},
inlineEditing: {
keys: true
}
}).jqGrid("navGrid").jqGrid("inlineNav");
beforeSaveRow: myBeforeSaveRow 选项被移除.
