Is it possible to tell onChange to only change a specific form?
I have 2 forms and currently have this code CODE onChange="if(this.value != -1) window.location='diskusjontest.php?id=' + this.value;"> Is there anything I can replace windoe.location='diskusjontest.php etc. with to make it only fill out form2 not form1? Thanks:) This post has been edited by Mr Me: Nov 15 2009, 07:51 AM |

Depends on what you mean with change. Replace the whole form with another one? Possible, yes. Easily done, no.

I just want it to fill another set of text into another form on the same page.
As it works now, I have a dropdown box, when I select a value from that, it fills out 3 text boxes with data from a database, but now I need a second set of boxes and drop down list, the list contains the same data, but when I select a different name in the list I want it to fill that info to the other set of text boxes. There is no way to make it from this?: CODE onChange="if(this.value != -1) window.location='diskusjontest.php?id=' + this.value;"> into something like this: CODE onChange="if(this.value != -1) myboxes.location='form2' + this.value;"> This post has been edited by Mr Me: Nov 15 2009, 07:24 AM |

Sure, but not with location as location refers to the document's URL. The form is part of the page. It doesn't have an URL. There are different ways to access a the value of a form control. Maybe you'd better read from the start.

Did read through your links, not much that have to do with the onChange command, but I tried changing the location into this:
CODE onchange="if(this.value != -1) document.forms[0] + this.value;"> to get it to change values in the first form on the page, but not working. The script I did use worked, but as it used location it does reload the entrire page and thats not what I want. I have 2 drop down boxes, they fetch data from a database and when you select a name in the drop down it fetch rest of the data ($first $last $phone etc) and those data should be displayed in textboxes on the page (and they do with old script, but thats not working when I put 2 boxes there). This is so that you can save often used data into the databse and just get them by selecting a name in the drop down. I just want the onChange command to "understand" that is's should change the form1, instead if reloading the enitre page. |

I have a dropdown box, when I select a value from that, it fills out 3 text boxes with data from a database, To access a database you must either submit the form or use AJAX. Since the onchange event is used with client-side javascript, that leaves you with AJAX. Or --if you know what data you'll need-- you might "prepare" the data from the database when the page is requested and store it in e.g. javascript arrays on the page until needed by the forms. QUOTE onchange="if(this.value != -1) document.forms[0] + this.value;"> You must specify which three(?) form fields in the form document.forms[0] you want to change the values of, specify those three values, and then use the correct operator for changing value. QUOTE when you select a name in the drop down it fetch rest of the data ($first $last $phone etc) Those look like server-side PHP variables. |
