这是我的表格，当用户点击你是会员问题IE是或否 在NO中，具有id cit的整个表行正在隐藏但是当用户单击是时它将再次显示整个表行但我的问题是当用户单击NO并且之后它将点击YES，表行显示但它显示我的宽度
<script>
function chk_register() {
if (document.getElementById('rchk1').checked) {
document.getElementById("cit").style.display = "block";
}
if (document.getElementById('rchk2').checked) {
document.getElementById("cit").style.display = "none";
}
}
function chk_register1() {
if (document.getElementById('rchk3').checked) {
document.getElementById("no").style.display = "block";
}
if (document.getElementById('rchk4').checked) {
document.getElementById("no").style.display = "none";
}
}
</script>
答案 0 :(得分：0)
您正在设置表格行<tr>以显示block以显示它。相反，您应该使用table-row，因为这是<tr>的默认值：
<强> Demo
function chk_register(){
if (document.getElementById('rchk1').checked) {
document.getElementById("cit").style.display = "table-row";
}
if (document.getElementById('rchk2').checked) {
document.getElementById("cit").style.display = "none";
}
}
function chk_register1(){
if (document.getElementById('rchk3').checked) {
document.getElementById("no").style.display = "table-row";
}
if (document.getElementById('rchk4').checked) {
document.getElementById("no").style.display = "none";
}
}
附注：您应该使用复选框onchange事件而不是onclick。
