i want to set a variables name dynamically, I've been trying:
var iframes = $('iframe').filter(function (index) {
return index == 0 || $(this).attr("current") == "no";
})
if(iframes.length >0){ //if one of the iframes hasnt got current set as current, use it
var theSuffix = iframes.attr('id').split('_').pop();
window['thisPreview'+theSuffix] = $fi.prev(".image-preview");
$hidden.closest(".file-upload-form").find(".variable-hidden").attr('value',theSuffix);
}
where I want a variable called 'thisPreview' and then a number, which will be the id of the matched div, or the variable 'theSuffix' (variable needs to be global, too).
how can I achieve this?

Don't make variables that have a common prefix and numbers at the end. Just use an object:
var thisPreview = {};
...
thisPreview[theSuffix] = $fi.prev(".image-preview");
