    <p>I have a function that creates an array that contains the return value from the HTML DOM method : window.document.getElementById()</p> <pre><code>function makearray1(){ var array1=[1,window.document.getElementById('divID'),['a','b'],[1,2]]; } </code></pre> <p>then I pass the array into another function</p> <pre><code>use(array1) function use(xxx){ xxx[1].innerHTML=xxx[2][0]; } </code></pre> <p>and 'a' is written in the appropriate div</p> <hr> <p>later I decided to put the array in a form and post it to a txt file on the server using php and:</p> <pre><code>JSON.stringify(array) </code></pre> <hr> <p>So now I use AJAX to call the data from the txt file after the rest of the page has loaded etc... and the original function used to make the array is not included at all. </p> <p>so my php is basically this:</p> <pre><code> $a1='use('; $data1 =file_get_contents("text_file.txt") ; $a2=')'; echo $a1.$data1.$a2; </code></pre> <p>and the response text:</p> <pre><code> var n= XMLHttpRequestObject.responseText; eval(n); </code></pre> <p>which pretty much means this:</p> <pre><code> use(text_file) function use(xxx){ xxx[1].innerHTML=xxx[2][0]; } </code></pre> <hr> <p>the problem is that the array in the text file looks like this:</p> <pre><code> [1,null,['a','b'],[1,2]] </code></pre> <p>instead of:</p> <pre><code> [1,window.document.getElementById('divID'),['a','b'],[1,2]] </code></pre> <hr> <p>My question: Is there any way that I can do the equivalent of what I'm trying to do here, which is immediately replicate the return value of the HTML/DOM method in an array using AJAX/php?</p> <p>To clarify: this is a simple example. I actually have a huge, multidimensional array that already has established pointers, or prefetched DOM nodes in it. Now I'm trying to replicate the array when a text version is loaded using ajax. I'm looking for a recursive approach to changing all of the null assignments with something that will immediately fetch the appropriate DOM node. Most likely I will need to do it with the response text, but was hoping I could do it with the php portion. </p>

    1. CO_"I have a function that creates an array that contains the HTML DOM method: `window.document.getElementById()`"_ - No you don't. You create an array that contains the return value from `getElementById()`, which will either be a reference to a specific DOM element or `null` if no element has the specified id. And a DOM element won't be stringified.

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.
