    <p>I have function that returns an array of numbers. Next I have to display same number of stars in the related result id. As a complete noob in JavaScript(still struggling with validations:P ) I tried many things to no avail. Hopefully the code snippets(current state) below will clear my issue - </p> <pre><code>function display(name1, number1, sign1, name2, number2, sign2, check, y_nat, o_nat) { document.getElementById("yname").innerHTML = name1 ; document.getElementById("ynumber").innerHTML = number1 ; document.getElementById("ysign").innerHTML = sign1 ; document.getElementById("oname").innerHTML = name2 ; document.getElementById("onumber").innerHTML = number2 ; document.getElementById("osign").innerHTML = sign2 ; document.getElementById('result').innerHTML = check + '%'; /* I am trying to display y_nat[0] Stars in the result id - yr by calling a show_image(id, number) function! */ x = "yr"; document.getElementById("yr").innerHTML = show_image(x ,y_nat[0]) ; x = "yl"; document.getElementById("yl").innerHTML = y_nat[1] ; x = "yf"; document.getElementById("yf").innerHTML = y_nat[2] ; x = "yp"; document.getElementById("yp").innerHTML = y_nat[3] ; x = "ys"; document.getElementById("ys").innerHTML = y_nat[4] ; x = "yi"; document.getElementById("yi").innerHTML = y_nat[5] ; x = "or"; document.getElementById("or").innerHTML = o_nat[0] ; x = "ol"; document.getElementById("ol").innerHTML = o_nat[1] ; x = "of"; document.getElementById("of").innerHTML = o_nat[2] ; x = "op"; document.getElementById("op").innerHTML = o_nat[3] ; x = "os"; document.getElementById("os").innerHTML = o_nat[4] ; x = "oi"; document.getElementById("oi").innerHTML = o_nat[5] ; } function show_image (id,number) { var img = document.createElement("img"); img.src = "stars2.png"; x = number; y = id; for (i =0; i&lt;x; i++){ document.getElementById(y).appendChild(img); } }//or something of this sort </code></pre> <p>Please let me know if the issue is unclear. I am still trying to solve it and will be really obliged someone can guide in this. I am trying to learn JavaScript. I am trying to use the code from the following link. <a href="http://www.codingforums.com/archive/index.php/t-94715.html" rel="nofollow">http://www.codingforums.com/archive/index.php/t-94715.html</a></p> <p>Thanks in advance.</p>

    1. COWhat happens when you execute your script? Are you sure that y_nat[0] returns a valid number? How do you call your "display" function? Are you sure it is even executed? Are you sure "stars2.png" is in the same folder as your html-file? (just some ideas of what could be wrong). Please give some more details.

    2. CO@Preli: Yup y_nat[0] returns a valid number which I am able to display. This code is not running but if I use document.getElementById("yl").innerHTML = y_nat[1] ;etc. it will display the number in the id. stars2.png is there in the same folder. Display function is being called from a compute() function which is called on a form submit. Hope this information helps.

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.
