我的 HTML 代码:
<div class="input-main">
<div class="block">
<div class="input-quest">What is your server OS</div>
<div class="input-resp">
<input onClick="os_others();" type="radio" name="button2" value="Yes" <?php if(!isset($_POST['button2']) || (isset($_POST['button2']) && $_POST['button2'] == 'Yes')) echo ' checked="checked"'?> checked /><label>Others</label>
<input onClick="os_hpux();" type="radio" name="button2" value="No" <?php if(isset($_POST['button2']) && $_POST['button2'] == 'No') echo ' checked="checked"';?> /><label>HP-UNIX</label>
</div>
</div>
<div id="lunidlist" >
<div class="block-with-text-area">
<div class="input-quest-with-text-area">Enter your LUN IDs in Hex(one ID in one line)</div>
<div class="input-resp-with-text-area"><span><textarea class="textarea" id="lunids" name="lunids" type="text"><?php if(isset($_POST['lunids'])) { echo htmlentities ($_POST['lunids']); }?></textarea></span> </div>
</div>
</div>
<div id="hpux-details-lunlist"style="display:none;" >
<div class="block-no-height">
<div class="sub_headings">Enter your vbus,target and LUN ids(one in one line)</div>
<div class="hupux-wrap-textarea">
<div class="hpuxleft">
<div class="input-quest-hpux-vbus-textarea">Vbus<br/>( 0 - F )</div>
<div class="input-resp-hpux-vbus-textarea"><span><textarea class="textarea" id="vbus-id-list" name="vbus-id-list" type="text"><?php if(isset($_POST['vbus-id-list'])) { echo htmlentities ($_POST['vbus-id-list']); }?></textarea></span> </div>
</div>
<div class="hpuxright">
<div class="input-quest-hpux-lun-textarea">LUN ID(In Hex)<br/>( 0 - 7 )</div>
<div class="input-resp-hpux-lun-textarea"><span><textarea class="textarea" id="lun-id-list" name="lun-id-list" type="text"><?php if(isset($_POST['lun-id-list'])) { echo htmlentities ($_POST['lun-id-list']); }?></textarea></span> </div>
</div>
<div class="hpuxcenter">

</div>
</div>
</div>
</div>
<div id="error1" style="display:none;"></div>
</div>
在上面的代码中,我在 div id 中有 3 个文本区域hpux-details-lunlist
。如果这三个文本区域中的行数不相等,代码将给出错误消息Mismatch between VBUS ID, Target ID and LUN ID Counts
。此错误消息回显到另一个 diverror1
javascript:
function os_hpux() {
$('#lunids').slideUp("fast");
$('#hpux-details-lunlist').slideDown("fast");
document.getElementById("lunids").value="";
$('#lunids').attr("disabled","disabled");
$('#hpux-details-lunlist').removeAttr("disabled");
}
function os_others() {
$('#lunids').slideDown("fast");
$('#lunids').removeAttr("disabled");
$('#hpux-details-lunlist').slideUp("fast");
$('#hpux-details-lunlist').attr("disabled","disabled");
document.getElementById("vbus-id-list").value="";
document.getElementById("lun-id-list").value="";
document.getElementById("target-id-list").value="";
}
function fun_vcount() {
vcount = 0;
var lines = $("#vbus-id-list").val().split("\n");
for (var i = 0; i < lines.length; i++) {
if (lines[i].length > 0) vcount++;
}
}
function fun_tcount() {
tcount = 0;
var lines = $("#target-id-list").val().split("\n");
for (var i = 0; i < lines.length; i++) {
if (lines[i].length > 0) tcount++;
}
}
function fun_lcount() {
lcount = 0;
var lines = $("#lun-id-list").val().split("\n");
for (var i = 0; i < lines.length; i++) {
if (lines[i].length > 0) lcount++;
}
}
$("#vbus-id-list").keyup(function () {
fun_vcount()
fun_tcount()
fun_lcount()
var message;
if(((vcount ==tcount) && (vcount == lcount)) || (!$("#vbus-id-list").val()) || (!$("#target-id-list").val()) || (!$("#lun-id-list").val()) || ($("#hpux-details-lunlist").attr("disabled") == "disabled")) {
$("#error1").slideUp("fast");
}
else{
message ="Mismatch between VBUS ID, Target ID and LUN ID Counts";
$("#error1").slideDown("fast");
document.getElementById('error1').innerHTML=message;
}
});
$("#target-id-list").keyup(function () {
fun_vcount()
fun_tcount()
fun_lcount()
var message;
if(((vcount ==tcount) && (vcount == lcount)) || (!$("#vbus-id-list").val()) || (!$("#target-id-list").val()) || (!$("#lun-id-list").val()) || ($("#hpux-details-lunlist").attr("disabled") == "disabled")) {
$("#error1").slideUp("fast");
}
else{
message ="Mismatch between VBUS ID, Target ID and LUN ID Counts";
$("#error1").slideDown("fast");
document.getElementById('error1').innerHTML=message;
}
});
$("#lun-id-list").keyup(function () {
fun_vcount()
fun_tcount()
fun_lcount()
var message;
if(((vcount ==tcount) && (vcount == lcount)) || (!$("#vbus-id-list").val()) || (!$("#target-id-list").val()) || (!$("#lun-id-list").val()) || ($("#hpux-details-lunlist").attr("disabled") == "disabled")) {
$("#error1").slideUp("fast");
}
else{
message ="Mismatch between VBUS ID, Target ID and LUN ID Counts";
$("#error1").slideDown("fast");
document.getElementById('error1').innerHTML=message;
}
});
我面临的问题:
我能够显示textareasvbus-id-list
和target-id-list
. lun-id-list
但是当我尝试使用第一个单选按钮隐藏这些文本区域时(在选择 时os_others()
,隐藏hpux-details-lunlist
)我能够隐藏文本区域,但错误消息没有隐藏。它仍然会显示消息Mismatch between VBUS ID, Target ID and LUN ID Counts
如果你看到我上面的代码,我已经包含($("#hpux-details-lunlist").attr("disabled") == "disabled"))
了,如果这真的隐藏了 div error1
。但这对我不起作用。错误信息一直显示在那里?我该如何隐藏它?
