如何使用JavaScript根据字符数拆分字符串

Question

I'm trying to take one string and split it into different chunks, and place it inside divs. Here's my code:

var simple = '<?php echo $hallo; ?>';     
var $div = $('#mybook');

if ($div.text().length > 50) {
    var limit = simple.lenght = 10;
    $(simple.split(limit)).each(function() {
        $('#mybook').append('<div>'+this+'</div>')
    });
}

Thank you, any help is appreciated.

Answer 1

Something like this should do the work:

<script type="text/javascript">
var simple = '<?php echo $hallo; ?>';
var $div = $('#mybook');
if($div.text().length > 50) {
    var limit = simple.lenght = 10;
    var regex = new RegExp('.{1,'+limit+'}','g')
    $(simple.match(regex)).each(function(key,val){
        $('#mybook').append('<div>'+val+'</div>')
    })
}
</script>

Answer 2

just split your string with a regex, not with split

$(simple.match('/.{'+limit+'}|.{,'+(limit-1)+'}$/g')).each(function() {

    $('#mybook').append('<div>'+this+'</div>')

});
