Well you can just use &lt;input type=&quot;text&quot; name=&quot;data&quot; value=&quot;&quot;&gt; and they cannot use carriage return at all. Or you can do:<br />
<br />
for(i=0; i&lt;str.length; i++){<br />
&nbsp; &nbsp; if(str.indexOf(&quot;\n&quot;) &gt;&nbsp;-1){<br />
&nbsp; &nbsp; &nbsp; &nbsp; str= str.replace(&quot;\n&quot;, &quot;&quot;);<br />
&nbsp; &nbsp; }<br />
}<br />
<br />
That code is from memory, so you might want to play around which it. The ascii character for carriage return is 13, so I think you can do replace(chr(13), '') and achieve the same effect.

<div>
Like this:<br />
<br />
&lt;input type=&quot;text&quot; name=&quot;yourText&quot; size=&quot;90&quot; maxlength=&quot;90&quot;&gt;<br />
<br />
And if you have to use textarea, then check this:<br />
&lt;textarea name=&quot;yourArea&quot; onKeyUp=&quot;if(this.value.mat<wbr />ch(/[\n\r]<wbr />/))this.va<wbr />lue=this.v<wbr />alue.repla<wbr />ce(/[\n\r]<wbr />/g,'');if(<wbr />this.value<wbr />.length&gt;90<wbr />)this.valu<wbr />e=this.val<wbr />ue.substr(<wbr />0,90);&quot;&gt;&lt;/<wbr />textarea&gt;<br />
<br />

</div>


Like this:

<input type="text" name="yourText" size="90" maxlength="90">

And if you have to use textarea, then check this:
<textarea name="yourArea" onKeyUp="if(this.value.match(/[\n\r]/))this.value=this.value.replace(/[\n\r]/g,'');if(this.value.length>90)this.value=this.value.substr(0,90);"></textarea>

I have an input box for freetext. I am already blocking the number of characters the user is allowed to type.<br />
&nbsp;onkeypress=&quot;javascript:if(<wbr />this.value<wbr />.length &gt;= 90){return false};&quot;<br />
<br />
How do I check for when the Enter Key (Carriage Return) is pressed and block it?<br />
So that someone cannot enter<br />
<br />
texttexttext<br />
texttext<br />

<br />
Because it must be inline, like<br />
