free-jqgrid 中的日期 "less but not empty" 自定义搜索
Date "less but not empty" custom search in free-jqgrid
我正在使用 free-jqgrid 4.15.4 来显示数据。我需要使用 Date less but not empty
过滤器搜索日期列,但它没有正确过滤。结果它给了我比搜索日期大的日期。
以下代码用于日期列中的自定义过滤器:
customSortOperations: {
dlne: {
operand: "<!=''",
text: "Date less but not empty",
filter:function (options) {
var p = this.p, iCol = p.iColByName[options.cmName], cm = p.colModel[iCol],
newformat = cm.formatoptions != null && cm.formatoptions.newformat ?
cm.formatoptions.newformat :
$(this).jqGrid("getGridRes", "formatter.date.newformat"),
srcformat = cm.formatoptions != null && cm.formatoptions.srcformat ?
cm.formatoptions.srcformat :
$(this).jqGrid("getGridRes", "formatter.date.srcformat"),
fieldData = $.jgrid.parseDate.call(this, srcformat, options.item[options.cmName]),
searchValue = $.jgrid.parseDate.call(this, newformat, options.searchValue);
var retFData = convertD(fieldData), t = new Date(retFData);
if ((retFData.getFullYear() < searchValue.getFullYear()) && (retFData.getMonth() < searchValue.getMonth()) && (retFData.getDate() < searchValue.getDate())) {
return true
}
}
},
}
我用来将字符串转换为日期格式的convert
函数如下所示:
function convertD(dateField) {
var date = new Date(dateField),
mnth = ("0" + (date.getMonth() + 1)).slice(-2),
day = ("0" + date.getDate()).slice(-2);
// year= (date.getFullYear())
var retVal = [day, mnth, date.getFullYear()].join("/");
return retVal;
}
我借鉴了的想法并做了一些修改,但似乎无济于事。因此请求社区对此提供帮助。
dlne
的代码可以固定为例如以下内容:
dlne: {
operand: "<!=''",
text: "Date less but not empty",
filter: function (options) {
var p = this.p, iCol = p.iColByName[options.cmName], cm = p.colModel[iCol],
newformat = cm.formatoptions != null && cm.formatoptions.newformat ?
cm.formatoptions.newformat :
$(this).jqGrid("getGridRes", "formatter.date.newformat"),
srcformat = cm.formatoptions != null && cm.formatoptions.srcformat ?
cm.formatoptions.srcformat :
$(this).jqGrid("getGridRes", "formatter.date.srcformat"),
fieldData, searchValue;
// the exact condition to test for "empty" depend on the format of your data
if (!options.item[options.cmName]) {
return false; // ignore empty data
}
fieldData = $.jgrid.parseDate.call(this, srcformat, options.item[options.cmName]);
searchValue = $.jgrid.parseDate.call(this, newformat, options.searchValue);
return fieldData.getFullYear() < searchValue.getFullYear() ||
(fieldData.getFullYear() === searchValue.getFullYear() &&
fieldData.getMonth() < searchValue.getMonth()) ||
(fieldData.getFullYear() === searchValue.getFullYear() &&
fieldData.getMonth() === searchValue.getMonth() &&
fieldData.getDate() < searchValue.getDate());
}
}
