嗨我有一张桌子,我在这里做一些代码来改变桌子变得可编辑和可选择...... 我的要求是 1.当点击TR时它应该变成蓝色并再次单击另一个将显示蓝色的TR和旧的变为白色(威胁不可选)
我认为一些代码是可行的,但原因是我已经有了一些代码来选择我需要的TD我在这里很难我不能删除像TR选择这样的td选择

我刚刚对你的代码进行了一些修改。由于selected
,selected1
和selected2
具有相同的css属性。我只使用selected
课程。我在这样的js中进行了修改:
$(".selected1").removeClass('selected1')
$(this).addClass('selected1');
$(function() {
$(".cat").dblclick(function() {
var OriginalContent = $(this).text();
$(this).addClass("cellEditing1")
$(this).html("<input id='value' type='text' value='" + OriginalContent + "' />");
})
$('tr').click(function() {
$('.selected1').removeClass('selected1');
$(this).addClass('selected1');
});
$(".cat").on("click", function() {
$(".selected1").removeClass('selected1')
$(this).addClass('selected1');
});
$(".cat1").on("click", function() {
$('.selected1').removeClass('selected1')
$(this).addClass('selected1');
});
$("#key").click(function() {
var sl = parseInt($(".selected").css("padding-left"));
sl = sl >= 20 ? "20" : "+=20";
$(".selected").css({
"padding-left": sl
});
var sq = parseInt($(".selected2").css("padding-left"));
sq = sq >= 40 ? "40" : "+=20";
$(".selected2").css({
"padding-left": sq
});
$(".cat.selected").each(function() {
var prevTd = $(this).closest('tr').prev('tr').find('td:eq(' + $(this).index() + ')');
console.log('Current td index: ' + $(this).index());
console.log('Previous td content: ' + prevTd.text());
prevTd.addClass("mainfunctionstyle");
prevTd.find('input').addClass("mainfunctionstyle");
});
$(".cat1.selected2").each(function() {
var paddingLeftpl = parseInt($(this).css("padding-left"));
if (paddingLeftpl == 40) {
$(".selected2").addClass("taskstyle");
$(".selected2").find('input').addClass("taskstyle");
}
});
});
});

我认为您的问题出现在您的代码中:
$(".cat").on("click", function() {
$(this).removeClass('selected')
$(this).addClass('selected');
});
$(".cat1").on("click", function() {
$(this).removeClass('selected2')
$(this).addClass('selected2');
});
您不需要在td
元素上拥有一个侦听器,因为在执行该作业的tr元素上有一个元素。有一种叫做事件传播的东西,默认情况下,如果你单击一个元素,被点击元素的父元素也会触发它的click元素,因此如果你正在寻找,你不需要处理td
次点击操纵tr
。
$(function() {
$(".cat").dblclick(function() {
var OriginalContent = $(this).text();
$(this).addClass("cellEditing1")
$(this).html("<input id='value' type='text' value='" + OriginalContent + "' />");
})
$('tr').click(function() {
$('tr').removeClass('selected1');
$(this).addClass('selected1');
});
$("#key").click(function() {
var sl = parseInt($(".selected").css("padding-left"));
sl = sl >= 20 ? "20" : "+=20";
$(".selected").css({
"padding-left": sl
});
var sq = parseInt($(".selected2").css("padding-left"));
sq = sq >= 40 ? "40" : "+=20";
$(".selected2").css({
"padding-left": sq
});
$(".cat.selected").each(function() {
var prevTd = $(this).closest('tr').prev('tr').find('td:eq(' + $(this).index() + ')');
console.log('Current td index: ' + $(this).index());
console.log('Previous td content: ' + prevTd.text());
prevTd.addClass("mainfunctionstyle");
prevTd.find('input').addClass("mainfunctionstyle");
});
$(".cat1.selected2").each(function() {
var paddingLeftpl = parseInt($(this).css("padding-left"));
if (paddingLeftpl == 40) {
$(".selected2").addClass("taskstyle");
$(".selected2").find('input').addClass("taskstyle");
}
});
});
});

希望对你有帮助! 我使用了jquery的toggleclass:http://www.w3schools.com/jquery/html_toggleclass.as
toggleClass()方法在添加和删除一个或之间切换 来自所选元素的更多类名。
此方法检查每个元素是否有指定的类名。该 如果丢失则添加类名,如果已经设置则删除 - 这个 创造一个切换效果。
然而,通过使用&#34;开关&#34;参数,您只能指定 删除,或只添加一个类名。
$(document).ready(function() {
$('#example tbody').on( 'click', 'tr', function () {
$(this).toggleClass('highlighted');
} );
} );

.highlighted {
color: #261F1D;
