如何禁用文本輸入中顯示的值

Question

所以表真的應該像下面這樣當用戶訪問該頁面：

Marks Per Answer            Total Marks Marks Remaining 
(blank text input)             4    4 
(blank text input)             6    6 
(disabled text input = 4 (same value as under Total Marks))  4    0 

我的問題是，怎樣才能既以上步驟可以通過改變解決jQuery的下面：

$(function() { 
//alert("here");   
var questions = $('#markstbl td[class*="_ans"]').length; 

//disable single entry 
for (var i=0;i<=questions;i++){ 
if($("[class*=q"+i+"_mark]").length ==1){ 
var t_marks = $("[class*=q"+i+"_ans]").html(); 
//alert(t_marks); 
$("[class*=q"+i+"_mark]").val(t_marks).attr('readonly',true); 
//$("[class*=q"+i+"_mark]").attr('readonly',true); 
}      
} 

//find each question set and add listeners 
for (var i=0;i<=questions;i++){          
$('input[class*="q'+i+'"]').keyup(function(){ 
var cl = $(this).attr('class').split(" ")[1] 
var questionno = cl.substring(cl.indexOf('q')+1,cl.indexOf('_')); 
var tot_marks = $(".q"+questionno+"_ans_org").val(); 
//alert(tot_marks); 
var ans_t=0; 
$("[class*=q"+questionno+"_mark]").each(function(){ 
var num = (isNaN(parseInt($(this).val())))?0:parseInt($(this).val()); 
ans_t+=parseInt(num);        
}); 
ans_t=tot_marks-ans_t;        
//alert(ans_t); 
//var fixedno = tot_marks; 
var ans = ans_t; 
var answerText='<strong>'+ans+'</strong>'; 
$(".q"+questionno+"_ans").val(ans); 
$(".q"+questionno+"_ans_text").html(answerText); 
}); 
} 
}); 

下面是動態HTML表：

<form id="Marks" action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post"> 


<table border='1' id='markstbl'> 
<thead> 
<tr> 
<th class='questionth'>Question No.</th> 
<th class='questionth'>Question</th> 
<th class='answerth'>Answer</th> 
<th class='answermarksth'>Marks per Answer</th> 
<th class='totalmarksth'>Total Marks</th> 
<th class='noofmarksth'>Marks Remaining</th> 
</tr> 
</thead> 
<tbody> 
<?php 
$row_span = array_count_values($searchQuestionId); 
$prev_ques = ''; 
foreach($searchQuestionId as $key=>$questionId){ 

?> 

<tr class="questiontd"> 
    <?php 
    if($questionId != $prev_ques){ 
    ?> 
    <td class="questionnumtd" name="numQuestion" rowspan="<?php echo$row_span[$questionId]?>"><?php echo$questionId?> <input type="hidden" name="q<?php echo$questionId?>_ans_org" class="q<?php echo$questionId?>_ans_org" value="<?php echo$searchMarks[$key]?>"><input type="hidden" name="q<?php echo$questionId?>_ans" class="q<?php echo$questionId?>_ans" value="<?php echo$searchMarks[$key]?>"></td> 
    <td class="questioncontenttd" rowspan="<?php echo$row_span[$questionId]?>"><?php echo$searchQuestionContent[$key]?> </td> 
    <?php 
    } 
    ?> 
<td class="answertd" name="answers[]"><?php echo$searchAnswer[$key]?></td> 
<td class="answermarkstd"> 
<input class="individualMarks q<?php echo$questionId?>_mark_0" q_group="1" name="answerMarks[]" id="individualtext" type="text" /> 
</td> 
<?php 
    if($questionId != $prev_ques){ 
    ?> 
<td class="totalmarkstd" rowspan="<?php echo$row_span[$questionId]?>"><?php echo$totalMarks[$key]?></td> 
<td class="noofmarkstd q<?php echo$questionId?>_ans_text" q_group="1" rowspan="<?php echo$row_span[$questionId]?>"><?php echo"<strong>".$searchMarks[$key]."</strong>"?></td> 
<?php 
    } 
    ?> 
</tr> 
<?php 
$prev_ques = $questionId; 
} 
?> 
</tbody> 
</table> 
</form> 

在媽媽耳鼻喉科在jQuery的功能，我試圖用t_marks變量顯示在文本輸入的值，但是當我提醒t_marks

Answer 1

可以使用的只讀，而不是禁用

的變化是什麼都不顯示

$("[class*=q"+i+"_mark]").val(t_marks).attr("disabled","disabled"); 

要

$("[class*=q"+i+"_mark]").val(t_marks).attr('readonly',true); 

Answer 2

或者你可以讓它專注了，當它獲得焦點

<input type="text" id="myTxt" onfocus="$(this).blur()"/>
