Unable to set value using document.getElementById()

Unable to set value using document.getElementById()

Hi all

Trying to reset the "slider" as defined here back to the default value of "1"

CODE --> html

<div id="slider-wrapper">
<label for="fader" title="Click here to reset" onclick="scaleinvoice('1')">Zoom</label>
<input type="range" min="0.5" max="1.5" value="1" step="0.1" oninput="scaleinvoice(value)" id="fader">
<output for="fader" id="percent">100%</output>

Code is

CODE --> html

document.getElementById("content").value = "1"; 
and is called in the function scaleinvoice().

Unfortunately the value is not reset - ideas, please?

You accidentally cut off the HTML containing the tag with id="content" attribute. Please show that too so we see the full picture.


RE: Unable to set value using document.getElementById()


Thanks for your reply and apologies for the omission.

html is:-

CODE --> html

<div id="content">
   <div id="row_1_col_1"></div>
   <div id="row_1_col_2"></div>
   <div id="row_1_col_3"></div>
   <div id="row_1_col_4"></div>
   <div id="row_1_col_5"></div>
   <div id="row_1_col_6"></div>
   <div class="clear_left"></div>	

css is:-

CODE --> css

#content {
   z-index: -1;
   background-image: url('../pngs/mhinvoice.png');
   -ms-transform: scale(1,1); /* IE 9 */
   -webkit-transform: scale(1,1); /* Safari */
   transform: scale(1,1); /* Standard syntax */

But that is a div. 3eyes Those have no value attribute, so neither the HTMLDivElement object returned by document.getElementById("content") will handle such property.

Sure the tag with id="content" should not be an input tag instead ?

Or maybe your code should reference fader instead ?

CODE --> JavaScript ( fragment )

document.getElementById("fader").value = "1"; 


RE: Unable to set value using document.getElementById()


So obvious it's no true - using document.getElementById("content") a number of times in the function scaleinvoice() and somehow did not see the error.

CODE --> html

document.getElementById("fader").value = "1"; 

resolves the issue.

Many thanks for your fresh eyes.
