when populating the option object dynamically, I am not getting the expected result when the string contains &

string="This is Testing -> A & B ";
select = window.document.search.mySelect;
select.options.length = 0;
select.options[0]= new Option(string);

Prints option contains ->"This is Testing -> A & B ";
Not "This is Testing -> A & B "

Where as if I create it this way
<select name="mySelect">
<option>Apple &</option>
</select>

The reslting string is - > Apple &


Help.

when you use &amp; in the html page, the html renders it as the correct character which you are seeing when you har code it into the page. The problem with it when JavaScript adds it, it doenot go through that rendering and it displays as the string.

The only option I can think of is to create a function that does a find and replace when adding the string. This way you can display the correct characters. One other problem that the & character brings to the plate is in the query string if you are submitting the form that way.

Thanks Eric.
In the database, I have the data as 'Business & Unit'
And I am sending a list of bean objects to my JSP and I am iterating throught <html:iterate> tag to pupulate the options dynamicaly in the JSP.

When the <bean:write> tag prints the above data, its printing as
'Business & Unit'
I was expecting it to print as 'Business & Unit'

I am not aware how the bean tag prints the results. Is there a way I can make the data print the way it fetches it from database.

It worked, except when there are two occurances of '&' in the string.
It only replaces once.

regExp = /&/gi;
function DoReplace(xString){
return xString.replace('&','&');
}

}

How do search till the end of the sentence and replace all occurrences of & with &.

Also I did not understand /&/gi;

regExp = /&amp;/gi;

That should replace it multiple times. It is a regular expression....

That was harder then it should be with the forum changing the &amp; to the & sign. I did not think about that when I posted my solution at first!

lol

Glad I could help!
