阿賈克斯發佈但對象錯誤

Question

我正在發佈發佈問題。當我用按鈕增加總價值時，值顯示，但當我點擊請求按鈕，然後所有發佈更新但餘額不更新。我檢查數據庫插入到「你有轉移$ [對象對象]帳戶餘額」。請幫助解決問題並幫助我達到完美。

$(function(){ 
 
\t 
 
var theTotal = 10; 
 

 
$('.add').click(function(){ 
 
    theTotal = Number(theTotal) + Number($(this).val()); 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub1').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t }; 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub2').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t }; 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub3').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t }; 
 
    $('.total').text(theTotal.toFixed(2));

Answer 1

您發送整個單元中的數據。 我相信你只需要發送數據。你在做什麼var af = $（'。total'）.text（theTotal.toFixed（2））;您是在設置該元素的值並將該元素分配給一個變量。

記住的.text（東西）設定值

的.text（）得到值

$(function(){ 
 
var af; 
 
var theTotal = 10; 
 

 
$('.add').click(function(){ 
 
    theTotal = Number(theTotal) + Number($(this).val()); 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub1').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t } 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub2').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t } 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 
$('.sub3').click(function(){ 
 
\t if(theTotal > 10) { 
 
     theTotal = Number(theTotal) - Number($(this).val()); 
 
\t } 
 
    $('.total').text(theTotal.toFixed(2)); 
 
}); 
 

 

 
$('.total').text(theTotal.toFixed(2)); 
 
    \t $('#request').click(function(){ 
 
af = $('.total').text(); 
 
    console.log(af); 
 
\t \t $.ajax({ 
 
\t \t \t type:'POST', 
 
\t \t \t url:window.location.protocol+'//'+window.location.host+'/?add=fund', 
 
\t \t \t data:'qun='+af, 
 
\t \t \t cache:false, 
 
\t \t \t beforeSend:function(){ 
 
\t \t \t \t $('html *').addClass('op-progress'); 
 
\t \t \t }, success:function(html){ 
 
\t \t \t \t $('html *').removeClass('op-progress'); 
 
\t \t \t \t document.location.href=_url+'/?add=fund'; 
 
\t \t \t } 
 
\t \t }); 
 
\t }); 
 
\t 
 
});
