    <p>after trying to solve the problem without and with help I'm still stuck. My aim was writing a GM-script with JS. Someone told me to use jQuery because of its simplicity. Well, I started learning JS last week and my head is full of information. What I need is hint/start/beginning/whatever telling me how to rewrite the script into a fine working jQuery-script. Well, I read some manuals, but somehow I just cannot figure it out. It might be that I misunderstood the syntax of jQuery which can't be hard to unserstand. At least I relived the manuals...</p> <p>This is how the script should work: 1. I created 3 functions. One for checking whether the inputfields contain numbers and only allow digits, commas, points and some controls. A second to replace characters and alert if sth. is badly wrong. The third to sum up four fields and put the result in the fifth. 2.I created two functions for each field. One function hides the text, one function shows the text by clicking 'a'. 3. At least I created a table with all inputfields and text it should contain. 4. By clicking a special button the note appears(I still have to write that...)</p> <p>It's a big deal for me putting all the information together and writing a good and goodlooking(and I know it is not - yet) script.</p> <p>I really hope I you can help me. I just need a beginning...</p> <p>The following is the code I wrote. It won't work in GM because of the used document.write function because of the sandbox, etc. :-(</p> <p>checks whether the inputfields contain numbers, only allows digits, commas, points and some controls</p> <pre><code>function check(event) { var keycode; if (window.event) { keycode = window.event.keycode; } else if (event) { keycode = event.which; } else { return true; } if (47 &lt; keycode) { if (keycode &lt; 58) { return true; } } var keycodeascii = new Array(0,8,44,46); while (keycodeascii.length &gt; 0) { if (keycode == keycodeascii.pop()) { return true; } } return false; } </code></pre> <p>replaces any character by '.',doesn't allow characters at the beginning and end</p> <pre><code>function replace(id) { with(id) { var oldValue = value; var newValue = oldValue.replace(/\W+/g, "."); newValue = newValue.replace(/\W+$/g, ""); newValue = newValue.replace(/^\W/g, ""); value = newValue; //alerts if digits are split by more than character var digits = newValue.split("."); if (digits.length &gt;= 3) { alert("Sie haben " + (digits.length -1) + " Sonderzeichen verwendet. Bitte korrigieren Sie Ihre Eingabe."); field.focus(); } } } </code></pre> <p>sums up field1-field4, result appears in field5</p> <pre><code>function calculate() { var summe = (1*window.document.getElementById('field1').value) + (1*window.document.getElementById('field2').value) + (1*window.document.getElementById('field3').value) + (1*window.document.getElementById('field4').value);

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.
