在此代码中,如果任何表格单元格为空,则不允许保存,但是,我现在想要保存甚至最后一个表格单元格为空。
我如何在这里添加表格行的最后输入,其中类型不是 隐藏?
$('#myTable tr input[value != add]:text').filter(function () {});
查看我的FIDDLE
这是我的javascript代码:
$("#btnSave").click(function (event) {
var flag = false;
var emptyBoxes;
var $rows = $('#myTable tr:not(:hidden)');
$rows.each( function () {
emptyBoxes = $('#myTable tr input[value != add]:text').filter(function () {
return this.value == "";
});
if (emptyBoxes.length != 0) {
flag = true;
}
});
if (flag) {
alert("this cannot be empty");
emptyBoxes.eq(0).focus();
} else
alert("done");
});
答案 0 :(得分:2)
请尝试以下代码:
var fields = $('input[type=text]'); /* All fields */
/* This function will find empty fields */
var findEmptyFields = function() {
var n = fields.length - 1;
/* Go throw all inputs with type=text and if someone is empty return index of this element */
for (var i = 0; i < n; i++) {
if (fields.eq(i).val() === '') {
return i;
}
};
/* Else return false that means that we didn't find any empty fields*/
return false;
}
$("#btnSave").on('click', function() {
var empty = findEmptyFields();
if (empty === false) {
alert('Done');
}
else {
alert('Some field is empty');
fields.eq(empty).focus();
}
});
