Alert, confirm and prompt windows 100% SVG

New version runing with Firefox 1.5, Opera 9 and Batik 1.6

Design and script are separated.
Script is load on begin 
Design is load on request and removed after use.

You can create your design, save it in SVG or SVGZ files.

See example

In main SVG, for using alert, prompt or confirm, you have to
1) load script with 
    <script xlink:href="js/alert.js"/>    manage windows
    <script xlink:href="js/opera.js"/>    emulation for getURL() and parseXML()
    <script xlink:href="js/tools.js"/>    moving windows
2) reserve at the end place for design with <g id="messages" transform="translate(100,50)"></g> by example 
3) put in <defs> gradients used by design
4) call it with 
add_alert("svg/alert.svg","messages","Width of rectangle is\n"+large.toString());
in order: file for design, name of group where put fragment, string for text
or
add_confirm("svg/confirm.svg","messages","Change color\nof rectangle\nin green",num);
in order: file for design, name of group where put fragment, string for text, number for using
or
add_prompt("svg/prompt.svg","messages","Enter color\nof rectangle\nas red or #CCCC00",num);
in order: file for design, name of group where put fragment, string for text, number for using

5) create functions to use result in main SVG as this

function messages_use_confirm(result,num_w)
{
    if (!result)
        return
    switch(num_w)
    {
        case 0:
            obj=svgdoc.getElementById("rect");
            obj.setAttribute("fill","green");
            break;
        case 1:
            obj=svgdoc.getElementById("rect2");
            obj.setAttribute("width","200");
            break;
    }
}

function messages_use_prompt(result,data,num_w)
{
    if (!result)
        return
    switch(num_w)
    {
        case 0:
                obj=svgdoc.getElementById("rect3");
                obj.setAttribute("fill",data);
                break;
        case 1:
                obj=svgdoc.getElementById("rect4");
                obj.setAttribute("fill",data);
                break;
    }
}
