View 9 RepliesI have a fck editor in which the user enters some text. And in the code i want to strip the class,id attributes of the text posted. I know this can be done through regular expressions And i have written some code to do so but unfortunately it's not working.
private string RemoveScripts(string input)
{
string re1 = "(.*?"; // Non-greedy match on filler
string re2 = "(class)"; // Word 1
string re3 = "(=)"; // Any Single Character 1
string re4 = "(".*?"))"; // Double Quote String 1
string re5 = "(id)";
Regex regClass = new Regex(re1 + re2 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
Regex regID = new Regex(re1 + re5 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
input = regClass.Replace(input, new MatchEvaluator(ReplaceClassID));
input = regID.Replace(input, new MatchEvaluator(ReplaceID));

I am creating a web form for employees to submit recipe's on a web form. The fields are recipe name, ingredients, and the recipe instructions. Majority of the time, employee's will be copying/pasting the text from a word document. Currently I am using the ajax editor control. I know there is a "Paste from Word" button that can be used but all the users are not going to know to use the button.
They may just do a right click to paste or the ctrl v to paste. When this is done, all the html tags from Word are pasted as well. I want to be able to remove the tags.
I want to implement readmore/less feature. i.e I will be having html content and I am going to show first few characters from that content and there will be a read more link in front of it. I am currently using this code :
var txtToHide= input.substring(length);
var textToShow= input.substring(0, length);
var html = textToShow+ '<span class="readmore"> … </span>'
+ ('<span class="readmore">' + txtToHide+ '</span>');
html = html + '<a id="read-more" title="More" href="#">More</a>';
Above input is the input string and length is the length of string to be displayed initially. There is an issue with this code, suppose if I want to strip 20 characters from this string:
"Hello <a href='#'>test</a> output", the html tags are coming between and it will mess up the page if strip it partially. What I want here is that if html tags are falling between the range it should cover the full tag i.e I need the output here to be "Hello <a href='#'>test</a>" . How can I do this?
i'm doing ajax website using PostWebRequest() function, when i call any .aspx page to the target html element the output is coming fine in IE but in FF(FireFox) is coming in html format(html tags) IE output : [URL] FF output : [URL]
javascript functions :
function PostWebRequest(postPage, HTMLTarget, parameter) {
displayElement = $get(HTMLTarget);
displayElement.innerHTML = "<div style='text-align:center;'><br /><br /><br /><br /><br /><img src='images/ajax-loader.gif' algin='center' /></div>";
var wRequest = new Sys.Net.WebRequest();
wRequest.set_url(postPage);
wRequest.set_httpVerb("POST");
var body = parameter;
wRequest.set_body(body);
wRequest.get_headers()["Content-Length"] = body.length;
wRequest.add_completed(onWebRequestCompleted);
wRequest.invoke();
}
function onWebRequestCompleted(executor, eventArgs) {
if (executor.get_responseAvailable()) {
if (document.all) {
displayElement.innerHTML = executor.get_responseData();
}
else {
displayElement.textContent = executor.get_responseData();
}
}
else {
if (executor.get_timeOut()) {
alert("Timed Out");
}
else {
if (executor.get_aborted())
alert("Aborted");
}
}
}

View 3 RepliesI have a text area in my ASP.NET web application that is used to enter html code. Now there is also an button control, which upon clicking should retrieve just the text placed between certain html tags in the text box. For example:
1) User types html code including tags etc. and clicks the OK button
2) In my code the text from the text area is retrieved and only the part between a <p></p> tag should be saved to a string object.
I can obviously get the text from the text area and attach it to a string object but I am not able to work out how to just get text within a certain html tag like <p></p>
