  1. POJavascript search for substring
    text
    copied!<p>I am trying to write a javascript function that will search all of the specified divs in a html page for the substring contained in my search bar. How can I do this simply? </p> <p>Here is my code so far, I have it working so that the <code>showMe</code> method will only display the divs selected, I just need the substring code to work now. Could someone please help?</p> <pre><code> &lt;html&gt; &lt;head&gt; &lt;script type="text/javascript"&gt; &lt;!-- function dynamicSearch() { var val = document.getElementById('search').value; if (val == '') val = '-1'; var srch = new RegExp(val, "gi"); var els = document.getElementsByClassName('row'); for (var idx in els) { if (idx != parseInt(idx)) continue; var el = els[idx]; if (typeof(el.innerHTML) !== 'undefined') { console.log(el.innerHTML); if (srch.test(el.innerHTML)) { el.style.display = 'block'; } else { el.style.display = 'none'; } } } } function showMe (it, box) { var vis = (box.checked) ? "block" : "none"; document.getElementById(it).style.display = vis; } //--&gt; &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form&gt; &lt;label for="search"&gt;Search:&lt;/label&gt; &lt;input type="text" name="search" id="search" onkeyup="dynamicSearch()"/&gt; &lt;input type="checkbox" name="modtype" value="value1" onclick="showMe('div1', this)" /&gt;value1 &lt;input type="checkbox" name="modtype" value="value2" onclick="showMe('div2', this)" /&gt;value2 &lt;input type="checkbox" name="modtype" value="value3" onclick="showMe('div3', this)" /&gt;value3 &lt;input type="checkbox" name="modtype" value="value4" onclick="showMe('div4', this)" /&gt;value4 &lt;input type="checkbox" name="modtype" value="value5" onclick="showMe('div5', this)" /&gt;value5 &lt;div class="row" id="div1" style="display:none"&gt;Show Div 1&lt;/div&gt; &lt;div class="row" id="div2" style="display:none"&gt;Show Div 2&lt;/div&gt; &lt;div class="row" id="div3" style="display:none"&gt;Show Div 3&lt;/div&gt; &lt;div class="row" id="div4" style="display:none"&gt;Show Div 4&lt;/div&gt; &lt;div class="row" id="div5" style="display:none"&gt;Show Div 5&lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>
