向表中的某些单元格添加删除线功能 [英] Adding strike-through feature to certain cells in Table
问题描述
我有一个函数，可以根据用户在文本框中输入的数字来创建一定数量的单元格.我试图获取它，以便在单击阴影均匀行"按钮时，每个其他单元格都可以通过，但没有运气.我觉得使用i％2 === 0是获取要插入行的单元格的正确方法，但是不确定要放入的特定参数.任何建议都将有所帮助！
I have a function that creates a certain number of cells based on the number a user enters into a text box. I am trying to get it so that when the "Shade even Rows" button is clicked, every other cell gets a line-through, but am not having luck. I feel like using i % 2 === 0 is the right way to get the cells I want to put a line-through, but not sure of the specific parameters to put in. Any suggestions would help!
$(document).ready(function() {
$('#nbrTxt').focus();
function addItem() {
var value = $('#nbrTxt').val();
var usrName = prompt("Name?");
$('#buttons').append('<li><button class="shade">Shade Even Rows</button><button class="drkLine">Show Dark Line Every 10 Rows</button></li>')
for (var i = 1; i <= value; i++) {
$('table').append('<tr><td></td><td></td></tr>');
$('table tr:last td:first').html(i);
$('table tr:last td:last').html(usrName);
$(this).focus().select();
$('#nbrTxt').val("");
};
};
$('#btnGo').click(addItem);
$('#nbrTxt').keydown(function(e) {
if (e.which === 13)
addItem();
})
$(document).on('click', '.shade', function() {
if (('#nbrTxt').val() % 2 === 0) {
$(this).closest("tr").css('textDecoration' === 'iine-through');
}
})
});

推荐答案
.css('textDecoration' === 'iine-through');无效，无法设置元素的css属性；参见 .css() .
.css('textDecoration' === 'iine-through'); is not valid procedure to set css property of element; see .css() .
尝试使用:even选择器
$("tr:even").css("textDecoration", "line-through")
