    <p>I'm developing an android app with phonegap. I'm making an HTML table with some that with a <code>for</code> loop from localStorage. I need, for each row, to store the index i of the <code>for</code> to use it for retrieving an item from localStorage that has the name like the index. I have some code but the variable that i defined for that effect gets overwritten by the loop (of course). Here's the code:</p> <pre><code>&lt;script language="javascript"&gt; if(len != 0) { var table = document.getElementById('hor-minimalist-b'); // get the table element var tableBody = table.childNodes[1]; // get the table body var tableHead = table.childNodes[0]; // get the table head var thead = document.createElement('th'); var row2 = document.createElement('tr'); // create a new row var headText = document.createTextNode('Dados'); thead.scope = "col"; thead.appendChild(headText); row2.appendChild(thead); tableHead.appendChild(row2); for (var i=0; i&lt;len; i++) { var row = document.createElement('tr'); // create a new row var cell = document.createElement('td'); // create a new cell var a = document.createElement('a'); var cellText = document.createTextNode(localStorage.getItem('key' + i)); var xyz = "key" + i; a.href = "alterar.html"; a.onclick = function() { doLocalStorage(xyz) }; a.appendChild(cellText); cell.appendChild(a); // append input to the new cell row.appendChild(cell); // append the new cell to the new row tableBody.appendChild(row); // append the row to table body }} &lt;/script&gt; &lt;/table&gt; </code></pre> <p>Maybe i'm not explaining myself too well. If you need any more info please ask. Thanks in advance. Eva</p>

    1. COI am confused about your question... why do you need to store it? Where do you need to store it? Can you make it a global var, or an attribute of some element?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
