首先，在頁面加載，我設置的默認水印如下：水印模糊後重置
function AddWatermarksDataEntry() {
initialWatermarks = new Array();
initialWatermarks.push(new Array("P1_BIRTHDATE_MASK", "__/__/____"));
initialWatermarks.push(new Array("P2_BIRTHDATE_MASK", "__/__/____"));
initialWatermarks.push(new Array("P1_VALIDFROM_MASK", "~#SF_DD/MM/YYYY~"));
initialWatermarks.push(new Array("P2_VALIDFROM_MASK", "~#SF_DD/MM/YYYY~"));
initialWatermarks.push(new Array("P1_IDENTITYDOCUMENTNUMBER", " "));
initialWatermarks.push(new Array("P2_IDENTITYDOCUMENTNUMBER", " ")); //***-*******-**
initialWatermarks.push(new Array("P1_VAT", "~#SF_9OR10_DIGIT~"));
initialWatermarks.push(new Array("P2_VAT", "~#SF_9OR10_DIGIT~"));
Watermarker(initialWatermarks);
}
後來，當我爲我的身份證類型 調整下拉值我做到以下幾點：
if(newIdentityDocumentType == "1")
{
ChangeIdentityDocumentNumberField($('#'+ whichPerson +'_IDENTITYDOCUMENTNUMBER'), $('#'+ whichPerson +'_NATIONALITY'), watermarkIdentityDocumentNumberBelgian, foreignPersonWaterMark, 14, 14);
$('#'+ whichPerson +'_IDENTITYDOCUMENTNUMBER').mask('999-9999999-99');
$('.'+ whichPerson + '.identityDocumentNumber').text('e.g. 123-456789112-34');
}
我檢查用戶是否選擇了正確的身份證件類型。如果他或她做了，則更改輸入字段的屬性，具體來說，我希望調整水印。
的ChangeidentityDocumentField方法調用，將改變這樣的水印方法：
function ChangeIdentityDocumentNumberField(IdentityDocumentNumberField, NationalityField, WatermarkBelgian, WatermarkForeign, MaximumBelgian, MaximumForeign) {
if (NationalityField.val() == "0") {
//omitted code
ChangeWatermark(IdentityDocumentNumberField, WatermarkBelgian);
} else {
//omitted code
ChangeWatermark(IdentityDocumentNumberField, WatermarkForeign);
}
}
function Watermarker(newWatermark) {
for (i = 0; i < newWatermark.length; i++) {
$('#' + newWatermark[i][0]).Watermark(newWatermark[i][1]);
$('#' + newWatermark[i][0]).blur(function (item, watermark) {
return function() {
//if ($('#' + item).val() == '') {
$('#' + item).Watermark(watermark);
//};
};
} (newWatermark[i][0], newWatermark[i][1]));
};
}
用這種方法鋪設的問題，當我在輸入字段，我想走出去，上面的函數被調用，一切順利的話，我看到添加水印（當我調試，但這時，突然，當代碼跳轉到：
} (newWatermark[i][0], newWatermark[i][1]));
我的水印重置爲默認值！？
