【问题描述】:
我正在开发一个专门针对 IE8 的小型 Web 应用程序(我知道你们都已经感受到了痛苦)。在这个应用程序中,我有一个 Update“按钮”(单击时)会生成一个框,用户可以在其中单击 Yes 或 No。我使用 JavaScript 生成框和带有type="submit" 的input 标记。
这是一个sn-p的代码:
HTML
<form action="." method="POST" id="yield_curve_form" enctype="multipart/form-data">
<div class="fileUploadDiv">
<img id="yieldCurve" src="../img/market/yield_curve.jpg" alt="ZBPF Bond Market" >
<div class="fileUploadButton">
<span>Upload New Image</span>
<input type="file" name="image_file" accept="image/*" class="uploadInput">
</div>
<div class="fileUploadReq">
<p>Image Requirements:</p>
<ul>
<li>Format: .png, .jpg, .jpeg, .bmp, .tif, .tiff</li>
<li>Resolution: 650 x 383</li>
<li>Maximum size: 2.0 MB</li>
</ul>
</div>
</div>
<button type="button" class="marketUpdateButton" onclick="confirmUpdate('yield_curve');">Update</button>
JS
function confirmUpdate(name)
{
// Create a div element
var div = document.createElement('div');
// Give it an ID
div.id = 'preSubmitAlert';
// Create a child h2 tag
var h2 = document.createElement('h2');
h2.innerHTML = 'This is a permanent change';
// Create a child p tag
var pMessage = document.createElement('p');
pMessage.innerHTML = 'Did you double check the data? It is important the data is accurate before you submit it.';
// Create child input tags
var inputYes = document.createElement('input');
var inputNo = document.createElement('input');
// Set parameters for input tags
inputYes.type = 'submit';
inputYes.name = name + '_update';
inputYes.value = 'Yes. Update the data.';
inputYes.id = 'inputYes';
inputNo.type = 'button';
inputNo.value = 'No. Take me back, please.';
inputNo.id = 'inputNo';
// Append the children to
div.appendChild(h2);
div.appendChild(pMessage);
div.appendChild(inputYes);
div.appendChild(inputNo);
// Create the background for transparency (needed for IE8 support)
var bg_div = document.createElement('div');
bg_div.id = 'bg_div';
// Create a screen and append the above div to it
var screenDiv = document.createElement('div');
screenDiv.id = 'screenDiv';
// Appending div and bg_div to screenDiv
screenDiv.appendChild(div);
screenDiv.appendChild(bg_div);
// Appending screenDiv to the body tag
document.body.appendChild(screenDiv);
// This line needs a reference to the #screenDiv is, which is inserted in the DOM only in the above line.
inputNo.onclick = function(){destroyElement(document.getElementById('screenDiv'))};
inputYes.setAttribute('form', name + '_form');
}
问题
为什么<input type="submit" ...>点击后不提交数据?
Obs.:这段代码适用于所有其他浏览器,包括更高版本的 IE。
提前谢谢你。

-
将
screenDiv附加到表单中,而不是document.body。
