Question

我有一个有日期列的JQGrid。我使用日期格式化程序将日期格式化为m/d/Y格式。以前，如果源日期的格式与srcformat中传递的formatoptions不匹配，则不会格式化日期。 JQGrid v4.4.0现在尝试格式化日期，无论源格式如何，并提供了日期方式:-)。

我填入此列的日期可以是正确的格式（m/d/Y），也可以是我在srcformat（Y-m-dTH:i:s）中定义的格式。

JQGrid 4.4.0中是否有办法不尝试解析与srcformat不匹配的日期？

我的colModel def for column：

{name:"date", index:"date", label:"Date", width:85, jsonmap:"date", hidden: false, formatter:'date', sorttype: 'date', formatoptions:{srcformat:'Y-m-dTH:i:s', newformat:'m/d/Y'}, searchrules: { date: true } }

我解决了自己的问题：）

我创建了一个自定义格式化程序，并使用Datejs JQuery库来帮助解析日期。

格式化程序基本上只将日期格式化为m / d / Y格式，如果它是Y-m-dTH：i：s格式;否则，它假定它已经是m / d / Y格式并保留它。

/**
 * This function formats the date column for the summary grid.
 * 
 * The grid could be populated with dates that are in m/d/Y format or in Y-m-dTH:i:s format; need
 * to account for this; want the dates to end up being in m/d/Y format always.
 * 
 * @param cellvalue     is the value to be formatted
 * @param options       an object containing the following element
 *                      options : { rowId: rid, colModel: cm} where rowId - is the id of the row colModel is the object of the properties for this column getted from colModel array of jqGrid
 * @param rowObject     is a row data represented in the format determined from datatype option;
 *                      the rowObject is array, provided according to the rules from jsonReader
 * @return              the new formatted cell value html
 */
function summaryGridDateFormatter(cellvalue, options, rowObject) {

    // parseExact just returns 'null' if the date you are trying to 
    // format is not in the exact format specified
    var parsedDate = Date.parseExact(cellvalue, "yyyy-MM-ddTHH:mm:ss"); 

    // if parsed date is null, just used the passed cell value; otherwise, 
    // transform the date to desired format
    var formattedDate = parsedDate ? parsedDate.toString("MM/dd/yyyy") : cellvalue;

    return formattedDate;
}

@icats：谢谢你！它确实有帮助 - 我开始感到非常沮丧...

我实际上必须稍微修改你的功能。我从数据库中获得了一个时间戳字段，该字段通过JSON返回为毫秒中的值（即表示实际值类似于：1343314489564）。因此，我为parsedDate添加了第二个检查，如下所示：

/**
 * This function formats the date column for the  grid.
 *
 * The grid could be populated with dates that are in m/d/Y format or in Y-m-dTH:i:s format; need
 * to account for this; want the dates to end up being in m/d/Y format always.
 *
 * @param cellvalue     is the value to be formatted
 * @param options       an object containing the following element
 *                      options : { rowId: rid, colModel: cm} where rowId - is the id of the row colModel is the object of the properties for this column getted from colModel array of jqGrid
 * @param rowObject     is a row data represented in the format determined from datatype option;
 *                      the rowObject is array, provided according to the rules from jsonReader
 * @return              the new formatted cell value html
 */
function dateFormatter(cellvalue, options, rowObject) {

    // parseExact just returns 'null' if the date you are trying to
    // format is not in the exact format specified
    var parsedDate = Date.parseExact(cellvalue, "yyyy-MM-ddTHH:mm:ss");
    if(parsedDate == null )
        parsedDate = new Date(cellvalue);

    // if parsed date is null, just used the passed cell value; otherwise,
    // transform the date to desired format
    var formattedDate = parsedDate ? parsedDate.toString("yyyy-MM-dd HH:mm:ss") : cellvalue;

    return formattedDate;
}

JQGrid 4.4.0：'date'格式化程序srcformat / newformat现在尝试在源日期格式与srcformat不匹配时格式化日期
