Count chars without spaces with AngularJs

Question

I need to count chars of a text with and with out spaces.

This is my attemp, but count the text without only the first space.

<div style="max-width:80%; margin: 10px auto">
<section class="row" ng-app="">
    <div class="col-lg-8">
        <div class="panel panel-default">
            <div class="panel-heading">Paste your text for <b>words count</b></div>
            <div class="panel-body">
                <textarea class="form-control" rows="10" ng-model="wordcounter"></textarea>
            </div>
        </div>
    </div>
    <div class="col-lg-4">
        <div class="panel panel-default">
            <div class="panel-heading">Words and characters</div>
            <ul class="list-group">
                <li class="list-group-item">Characters (with space)<span class="badge">{{wordcounter.length}}</span></li>
                <li class="list-group-item">Characters (no space)<span class="badge">{{wordcounter.replace(" ","").length}}</span></li>
            </ul>
        </div>

    </div>
</section>

Answer 1

You only replace one space

Without regex

The problem is that currently, you are only replacing one space instead of all the spaces in the string. One way you can solve this is by splitting the string by all spaces that are in the string str.split(" "); and then joining them together. (glueing the words together again without the space) with join.

Change your binding for the counter without spaces like this {{wordcounter.split(" ").join("").length}}

 <div style="max-width:80%; margin: 10px auto">
    <section class="row" ng-app="">
<div class="col-lg-8">
    <div class="panel panel-default">
        <div class="panel-heading">Paste your text for <b>words count</b></div>
        <div class="panel-body">
            <textarea class="form-control" rows="10" ng-model="wordcounter"></textarea>
        </div>
    </div>
</div>
<div class="col-lg-4">
    <div class="panel panel-default">
        <div class="panel-heading">Words and characters</div>
        <ul class="list-group">
            <li class="list-group-item">Characters (with space)<span class="badge">{{wordcounter.length}}</span></li>
            <li class="list-group-item">Characters (no space)<span class="badge">{{wordcounter.split(" ").join("").length}}</span></li>
        </ul>
    </div>

</div>
