    <p>I would like to delete selected rows in a table using javascript but problem is that once a row is deleted the index changes.</p> <p>This problem is confounded because only specific rows contain checkboxes and more checkboxes can be added.</p> <p><strong>I can already obtain all the correct row indexes I wish to delete</strong> inside of an array using javascript but then how would I then go about deleting the rows without hitting the wrong one and without using prototype or jquery. Purely javascript?</p> <p>Any help is greatly appreciated.</p> <pre><code> &lt;table class="example_table" id="mytable"&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="text" id="top row" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="button" onclick="addNewCheckboxRow()" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="button" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox" value="1" id="check1" /&gt;&lt;/td&gt; //row that may be deleted &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox" value="2" id="check2" /&gt;&lt;/td&gt; //row that may be deleted &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox" value="3" id="check3" /&gt;&lt;/td&gt; //row that may be deleted &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox" value="4" id="check4" /&gt;&lt;/td&gt; //row that may be deleted &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="button" /&gt;&lt;/td&gt; 7 &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>My current approach. not exact but you can get the drift.</p> <pre><code>var myrow=["6","7"]; document.getElementById("mytable").deleteRow(myrow[0]); //deletes row 6 document.getElementById("mytable").deleteRow(myrow[1]); //deletes row 7 But //the index has changed! //what happens when after the delete more rows are added! </code></pre>

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.
