Javascript / Client Side Development :: Problems with .bgColor


	Problems with .bgColor I am trying to change a group of background colors by calculating their names in a loop . Names are cfh13, cfh15, cfh17, etc... Unlooped code like cfh17.bgColor="#CCFFFF" ; works just fine. Code that does NOT involve a background color change but is calculated within a loop works just fine, such as... form[curedg + "s"]["value"] = "zorch" ; But this does not.... form["cfh" + 17]["bg.Color"] = "#CCFFFF" ; What am I doing wrong and how can I loop changing a named group of background colors? -- Many thanks, Don Lancaster voice phone: (928)428-4073 Synergetics 3860 West First Street Box 809 Thatcher, AZ 85552 rss: http://www.tinaja.com/whtnu.xml email: d@tinaja.com Please visit my GURU's LAIR web site at http://www.tinaja.com Don Lancaster said: - Hide quoted text - >I am trying to change a group of background colors by calculating their >names in a loop .

Your examples of what works and what doesn't should be more similar, in order to help to determine where the problem lies. There is no attribute named "bg.Color". If that was just a typo in your post, and doesn't appear in your code, then you need to learn to copy from your code and paste into your posts to avoid wasting everybody's time. Assuming that this also works: form["cfh17"]["bgColor"] = "#CCFFFF" ; then this should work: form["cfh" + 17].bgColor = "#CCFFFF" ; If the first case doesn't work, then the problem may be that cfh17 isn't a form element, so you can't access it via the form collection. -- - Hide quoted text - Lee wrote: > Don Lancaster said: >>I am trying to change a group of background colors by calculating their >>names in a loop .

The greater problem is to change the background colors of certain table cells by their input name with a loop, instead of one at a time. Unlooped code appears as a small part of http://www.tinaja.com/demo28a.asp -- Many thanks, Don Lancaster voice phone: (928)428-4073 Synergetics 3860 West First Street Box 809 Thatcher, AZ 85552 rss: http://www.tinaja.com/whtnu.xml email: d@tinaja.com Please visit my GURU's LAIR web site at http://www.tinaja.com Don Lancaster wrote on 20 mei 2007 in comp.lang.javascript: > .bgColor is an attribute of a table cell and seems to work properly > except as noted above.

Table cells do not have an input name. Is a loop not accessing one at a time? Perhaps you want this: var myCells = form["cfh" + 17].cells for (var n=0;n<myCells.length;n++) { if (myCells[n].name == 'blah') myCells[n].style.background-color = "#CCFFFF"; } not tested. -- Evertjan.
