Question

i use this code to get text of all nodes in body (Browser is IE8 it works on FF…)

thanks ,i develop a toolbar to change some texts in pages so if you have any other solution will made me happy,if i replace all of body with regex,it disable some futures of sites.for example in facebook if use replace all suggestion future will disable in friend finds section,so i want to change words step by step,it’s a filter for bad words

function replaceText(node)
{
 var textPropName = node.textContent === undefined ? 'innerText' : 'textContent';
 var childs = node.childNodes, i = 0;
 while(i < childs.length)    
 {
 alert(childs[i][textPropName]);
   if (childs[i][textPropName] !=null)
    {
      childs[i][textPropName] =childs[i][textPropName].replace(rgx,'new');
    }
    else
    {
      replaceText(document.body.childNodes[i]);} i++; 
    }
 }
}

it’s work and i can replace all text on a page but if a text be in out of tags same as belove i can’t access to it and replace it
problem: test5 ww tt xx test aren’t in any tag so they don’t replaced
any solution?
sincerely

<b>

  <h2> ppp gfdsgfds gf dg df   yyy old odld old</h2>

     yyy   yyy  yyy  yyy   old Click me! whatever
 </h1>
ppp  ppp ppp bwhoreface 
<b> 
ppp

end solution

function replaceText(node){ 
var textPropName = node.textContent === undefined ? 'innerText' : 'textContent';
   var childs = node.childNodes, i = 0;
var len= node.childNodes.length;
// alert('len='+len);
//var rgx = new RegExp('\\bold\\b', 'gi');
   while(node = childs[i]){
//alert('ee'+node.nodeType);  
if (node.nodeType == 3  ) {
//alert('!!!!!'+node.nodeValue );
//alert('ee'+node.nodeType); 
childs[i].nodeValue = childs[i].nodeValue.replace(rgx, 'newText'); 
} else { 
   replaceText(node); 

}

Here you go, this works in IE too…

Live Demo

function replaceText(node)
{
    var textPropName = node.textContent === undefined ? 'innerText' : 'textContent';
    var childs = node.childNodes, i = 0;
    var rgx = new RegExp('\\bff\\b|\\byyy\\b', 'gi');

    while(i < childs.length)    
    {
        if(childs[i].nodeType == 3) {
            alert(childs[i].nodeValue);

            childs[i].nodeValue = childs[i].nodeValue.replace(rgx,'new');
        } else {
            alert(childs[i][textPropName]);

            if (childs[i][textPropName] !=null)
            {
                childs[i][textPropName] =childs[i][textPropName].replace(rgx,'new');
            }
            else
            {
                replaceText(document.body.childNodes[i]);
            } 
        }

        i++; 
    }
}
