js function to clear field when action="onclick"

[swebster]

I could use some help to update these functions to only allow the clear and color update on the first onclick and not the second or third etc.

Upon entering the site the field includes some suggested text. When the onclick is issued the field updates and resets the color and text. What isn't required is if the field is clicked again no to repeat the color and text.

Suggestions?

function clearText(thefield) { 
    if (thefield.defaultValue == thefield.value) thefield.value = "" 
    else thefield.value = thefield.defaultValue 
} 
 
function changeInColor(thefield) { 
    if (thefield.defaultValue == thefield.value) 
      queryForm.QueryText.style.background= "#CCCCCC" 
    else queryForm.QueryText.style.background= "#FFFFFF" 
}

hi ...

for such a task the simplest solution is to init a global variable in page-init (may be onload of the page) with 0 and then when the field is clicked to increase the value by 1 ... and! ask for the value <= 1 to to the action else do nothing ... so its called only one time ...

kind regards
