動態創建控件

我想創建一個屏幕以輸入銷售訂單詳細信息。動態創建控件

我想盡可能快地

擰緊的過程所以我有兩個文本框

Product name   Qty +

表所以，如果我在+點擊我要創造條件，產品名稱的新文本框和數量。項目的數量可能是50或更多。我該怎麼做？

您可以使用jQuery。類似於

$('.plus').click(function() { 
    $(this).append('<input type="text">'); 
})

下面是一個使用克隆初始行的示例。 Try it live with jsFiddle。

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html lang="en"> 
<head> 
<title>Add Input Rows</title> 
<script type="text/javascript"> 
function addEvent(el, name, handler) 
{ 
    if (typeof window.addEventListener != "undefined") 
    { 
     el.addEventListener(name, handler, false); 
    } 
    else 
    { 
     el.attachEvent("on" + name, handler); 
    } 
}; 

addEvent(window, "load",function() 
{ 
    var productRows = document.getElementById("productRows"); 
    var clonedRow = productRows.getElementsByTagName("tr")[0].cloneNode(true); 
    addEvent(document.getElementById("addProductRow"), "click", function() 
    { 
     productRows.appendChild(clonedRow.cloneNode(true)); 
    }); 
}); 
</script> 
</head> 
<body> 

<table> 
<thead> 
    <tr> 
    <th>Product name</th> 
    <th>Qty</th> 
    <th><input type="button" id="addProductRow" value="+"></th> 
    </tr> 
</thead> 
<tbody id="productRows"> 
    <tr> 
    <td><input type="text" name="name"></td> 
    <td><input type="text" name="qty"></td> 
    </tr> 
</tbody> 
</table> 

</body> 
</html>

如果你想繼續，並添加刪除動態添加行的能力，你可以做這樣的事情（jsFiddle）：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html lang="en"> 
<head> 
<title>Add &amp; Remove Input Rows</title> 
<script type="text/javascript"> 
function addEvent(el, name, handler) 
{ 
    if (typeof window.addEventListener != "undefined") 
    { 
     el.addEventListener(name, handler, false); 
    } 
    else 
    { 
     el.attachEvent("on" + name, handler); 
    } 
} 

addEvent(window, "load", function() 
{ 
    var productRows = document.getElementById("productRows"), 
     templateRow = (function() { 
      var clonedRow = productRows.getElementsByTagName("tr")[0].cloneNode(true), 
       removeButton = document.createElement("input"); 
      removeButton.type = "button"; 
      removeButton.value = "-"; 
      removeButton.title = "Click to remove this row"; 
      clonedRow.getElementsByTagName("td")[2].appendChild(removeButton); 
      return clonedRow; 
     })(); 

    addEvent(document.getElementById("addProductRow"), "click", function() 
    { 
     var row = templateRow.cloneNode(true), 
      removeButton = row.getElementsByTagName("td")[2].getElementsByTagName("input")[0]; 
     addEvent(removeButton, "click", function() 
     { 
      productRows.removeChild(row); 
     }); 
     productRows.appendChild(row); 
    }); 
}); 
</script> 
<style> 
th.buttons input, td.buttons input { width: 100%; } 
</style> 
</head> 
<body> 

<table> 
<thead> 
    <tr> 
    <th>Product name</th> 
    <th>Qty</th> 
    <th class="buttons"><input type="button" id="addProductRow" title="Click to add a new row" value="+"></th> 
    </tr> 
</thead> 
<tbody id="productRows"> 
    <tr> 
    <td><input type="text" name="name"></td> 
    <td><input type="text" name="qty"></td> 
    <td class="buttons"></td> 
    </tr> 
</tbody> 
</table> 

</body> 
</html>

如果你想糾纏用戶惱人的彈出窗口如果他們嘗試刪除已填充的行，則交換此位（jsFiddle）：

addEvent(removeButton, "click", function() 
{ 
    var inputs = row.getElementsByTagName("input"), 
     confirmRemove = false; 
    for (var i = 0, input; input = inputs[i]; i++) 
    { 
     if (input.type == "text" && input.value !== "") 
     { 
      confirmRemove = true; 
      break; 
     } 
    } 

    if (!confirmRemove || 
     confirm("This row contains data. Are you sure you want to remove it?")) 
    { 
     productRows.removeChild(row); 
    } 
});
