I'm having a problem where I can't write the single quote character (' or ASCII ') into a macro input box (text or textMultiLine).

I get a javascript error upon updating the macro:

Line 89
Char: 251
Error: Expected ')'
URL: http://mysite/umbraco/dialogs/editMacro.aspx?mode=edit etc... etc...

Not sure what to do :-| something to do with the character not being escaped properly?

function saveTreepickerValue(appAlias, macroAlias) {
var treePicker = window.showModalDialog('treePicker.aspx?appAlias=' + appAlias, 'treePicker', 'dialogWidth=350px;dialogHeight=300px;scrollbars=no;center=yes;border=thin;help=no;status=no')
document.forms[0][macroAlias].value = treePicker;
document.getElementById("label" + macroAlias).innerHTML = "</b><i>updated with id: " + treePicker + "</i><b><br/>";
}

var macroAliases = new Array();

function registerAlias(alias) {
macroAliases[macroAliases.length] = alias;
}

function updateMacro() {
var macroString = '';

for (i=0; i<macroAliases.length; i++) {
var propertyName = macroAliases[i]
// Vi opdaterer macroStringen
if (document.forms[0][macroAliases[i]].type == 'checkbox') {
if (document.forms[0][macroAliases[i]].checked)
macroString += propertyName + "=\"1\" ";
else
macroString += propertyName + "=\"0\" ";

} else if (document.forms[0][macroAliases[i]].length) {
var tempValue = '';
for (var j=0; j<document.forms[0][macroAliases[i]].length;j++) {
if (document.forms[0][macroAliases[i]][j].selected)
tempValue += document.forms[0][macroAliases[i]][j].value + ', ';
}
if (tempValue.length > 2)
tempValue = tempValue.substring(0, tempValue.length-2)
macroString += propertyName + "=\"" + tempValue + "\" ";
} else {
macroString += propertyName + "=\"" + pseudoHtmlEncode(document.forms[0][macroAliases[i]].value) + "\" ";
}
}

if (macroString.length > 1)
macroString = macroString.substr(0, macroString.length-1);

if (document.forms[0].macroMode.value == 'edit') {
var idAliasRef = "";
if (document.forms[0]["umb_macroAlias"].value != '')
idAliasRef = " macroAlias=\"" + document.forms[0]["umb_macroAlias"].value;
else
idAliasRef = " macroID=\"" + document.forms[0]["umb_macroID"].value;

parent.opener.umbracoEditMacroDo("<?UMBRACO_MACRO" + idAliasRef +
"\" " + macroString +
">");
} else {
parent.opener.umbracoInsertMacroDo("<?UMBRACO_MACRO macroAlias=\"" + document.forms[0]["umb_macroAlias"].value +
"\" " + macroString +
">");
}
window.close()
}

function pseudoHtmlEncode(text) {
return text.replace(/\"/gi,"&amp;quot;").replace(/\</gi,"&amp;lt;").replace(/\>/gi,"&amp;gt;");
}
