JavaScript - Issue With String Search/regex
Hello all
I have search this topic but I can't really get a straightforward answer. I have been given a small assignment to make 4 checks. I'm not looking for handouts, the assignment itself is complete, but I just have this single problem. Check 1: make sure a radio button is checked (no problem) Check 2: make sure a string does not contain restricted characters (no problem) Check 3: make sure a string is of numbers only (issue 1) Check 4: make sure a string follows a certain format (issue 2) My problem lies with the <string>.value.search(/\D/) and <string>.value.search(/\d/). Dreamweaver does not want to recognize this as valid code. In turn, checks 3 and 4 do not execute. I have checked and re-checked for possible syntax errors, to no avail. I will attach my entire code and a screenshot of how Dreamweaver is handling my code. Code: <html>
<head>
<title>Payment Form</title>
<script type="text/javascript">
function errorCheck()
{
//start card must be checked
if ((document.form1.pmtType[0].checked == false) && (document.form1.pmtType[1].checked == false) && (document.form1.pmtType[2].checked == false) && (document.form1.pmtType[3].checked == false))
{
window.alert("Please select one of the credit cards")
return false
}
//end card must be checked
//start name character check
badChar = ";:!@#$%^*+?";length = badChar.length;
for (i=0; i<length; i++)
{
if (document.form1.Name.value.indexOf(badChar.charAt(i)) != -1)
{
window.alert("The name you entered contains illegal characters (;:!@#$%^*+?). Please re-enter your name")
document.form1.Name.focus()
document.form1.Name.select()

Thanks in advance, Matt Similar TutorialsFrom this string: "(EVAL)(H:somestring)Other Text here" I need to extract (H:somestring) and somestring into variables where somestring will could be and set of characters. Below is not working. Code: <script type="text/javascript"> var x = "(EVAL)(H:pines)Some other Text here"; alert(x.match(/H\:(.*?)/g)); </script> Thanks for any help or information. In this case, Let's take Google Search as example: The code is JScript .NET, which is basically a .NET version of Javascript. Regardless of language, Anyone with appending type of skill can answer my question. This code is used in Fiddler(It's a Man-in-the-middle proxy) Code: if (oSession.uriContains("&q=")) // oSession is a Fiddler object session // uriContains() function, checks for case-insensitive string from the URI
{
var str = oSession.fullUrl;
var sAppend = "test1+test2+test3";
if (!oSession.uriContains(sAppend))
{
oSession.fullUrl = str.replace( "&q=","&q="+sAppend);
}
}
For those who are confused, It says, If &q= is present in the URI, replace/append &q= with &q=test1+test2+test3 Problem: It appends test1+test2+test3 instantly, when it sees &q= in the URL. Basically, how do I make it wait until I click the submit/search button Thank you. Update: I heard about Onsubmit() event, but not really familiar with it. How do I use it? like, should I go to google source page and edit the form id? Also, Any other methods besides Onsubmit()? How do I replace the string "rpg" only present in between <et> tags ? Code: <et>ReplaceOnlyrpg</et> After replacement it should look like this Code: <et>ReplaceOnly</et> Any advice is appreciated. Thank you I am trying to grab all text between <START> and <END> and have the following bits of code, but neither are returning anything. I use JS so rarely that I can't see where the problems are - Code: var ermtext = response.match(/<START>(.*?)<END>/i);
if (ermtext) {
result.ermtext = ermtext.replace("$1");
}
Code: var patt=/<START>(.*?)<END>/i; result.ermtext = response.match(patt, "$1"); I am attempting to remove all HTML tags with nothing in the middle. For example, I want to remove this Code: <b><i><u> </u></i></b> I've written an expression that does that, but there's an issue with it. Here's my regex: Code: messageVal = messageVal.replace(/(<[^\/>]*>)+[\s]*(<\/[^>]*>)+/g,''); The issue is that I only want to delete as many end tags as I found open tags. An example that my regex doesn't work on is... Code: <b> hello <u><i> </i></u></b> The current regex will output: Code: <b> hello I need it to return: Code: <b> hello </b> Any ideas? I am using javascript to search for the '*' character in a string (ie. 'username*:') but using search('\*') does not work. How do I search for it since the search function takes a regexp argument and * messes that up?
I would like to find some direction or help to solve an issue I have. I would like to find a way to search for a string of content on my webpage and return the string, or at least part of the string into the URL... Example of the content on my page: ----- Welcome, John Adams Log Out Welcome to your own content, based on your settings provided. Feel free to download the content you need. ----- Fairly straightforward. Now I would like to create a function that will look at the page and "copy" the string of content beginning with "welcome" and ending with "out" Next, I would like to remove the "welcome," and "log out" and have the name remain. Then, post the name into the URL to be passed onto the next page for me to use as more personalization/dynamically driven content; Such as: http://www.noname.com/index.html?string=John-Adams Hopefully you can help. The code is JScript .NET, which is basically a .NET version of Javascript. Regardless of language, Anyone with appending type of skill can answer my question. The problem is, when I keep issuing the request it keeps appending over and over again Code: if (oSession.uriContains("search?q="))
{
var str = oSession.fullUrl;
var sAppend = "+test1+test2+test3";
if (!oSession.uriContains(sAppend))
{
oSession.fullUrl = str.replace( "search?q=","search?q="+sAppend);
}
}
Can you please give me an example? I'm still new to programming. Thank you Hi, I have a page with an iframe in it. I need my script to search the contents of the iframe for a specified string, and click the link within it. Here is my coding. Code: <script>
setTimeout(function() { window.location.reload(); }, 2000); // 2 seconds, e.g.
$(document).ready(function() {
$('a[href*="13468100"]', $("game").contents()).closest('tr').find('.fightActionInnerInner').parent("a").trigger("click");
});
</script>
</head>
<body>
<iframe src="http://vl.storm8.com/hitlist.php" width="100%" height="800px" id="game"></iframe>
In the post below is the content of the iframe. At the moment the script doesn't want to click the link, it just refreshes the page. Can anyone advise? Hey all, I'm in process of writing my own script (I don't want to use any jquery plugins) to render a table and allow for filtering/searching. So when user clicks on link, by default there will be parameters passed in query string as you can see in the setDefaults private method below. However, I'm stuck trying to figure out the best way to append values selected from filter dropdown to the query string. I know it will involve something along the lines of $("select").change(function(){var option = $(this).val()}). But I am having difficulty figuring out how to incorporate it with this. I would like to make use of the below buildFilter function somehow: Code: (function($){
var listview = $('#listview');
var lists = (function(){
var criteria = {
drop_filter: {
check: function(value){
if(value)
return
},
msg: "Loading..."
},
search_filter: {
check: function(value){
if(value)
return
},
msg: "Loading..."
}
}
var handleFilter = function(){
}
return {
create: function(component){
var component = component.href.substring(component.href.lastIndexOf('#') + 1);
return component;
},
setDefaults: function(component){
var parameter = {};
switch(component){
case "sites":
parameter = {
'order': 'site_num',
'per_page': '20',
'url': '/sites'
}
}
return parameter;
},
buildFilter: function(){
if(event == "change")
return criteria.drop_filter();
}
}
})();
$('#dashboard a').click(function(){
var currentComponent = lists.create(this);
var custom = lists.setDefaults(currentComponent);
initializeTable(custom);
});
var initializeTable = function(custom){
var defaults = {};
var query_string = $.extend(defaults, custom);
var params = [];
$.each(query_string, function(key,value){
params += key + ': ' + value;
})
alert(params);
}
})(jQuery)
Thanks for any response. Here is the link in question. I have created a small page with the isolated problem on it. http://frontendaudio.com/v/vspfiles/...pt_tester.html the javascript file that is referenced basically only does one thing. It searches for "> >" and then alerts us whether or not it's on the page. --- It pulls the innerHTML of the entire document --- the searches it - and indexes the string. I echoed the string out to a text area so you could see the string "> >" is clearly there after the word microphones in the link tag... </a> > < etc.. Any thoughts on how I can detect this string somehow? Thanks. Here is the code inside the javascript file. Code: var myStringDiscuss = 'microphones</a> >';
myStringDiscuss = myStringDiscuss.replace(/~/g,""); // unmunge
function discussDetection(){
var str = document.getElementsByTagName('html')[0].innerHTML;
str = str.toLowerCase(); // to make case insensitive
var category_string = str.indexOf(myStringDiscuss);
if (category_string == -1) {
alert("not on this page");
}
else {
alert("IS on the page");
}
}
window.onload= discussDetection;
Hey all, I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function: Code: <body> <select> <option value="createMsg">Add Message</option> <option value="removeMsg">Remove Message</option> </select> </body> Code: var menu = {
handleMenu : function(callback){
if(callback === "string"){
menu[callback]();
}
else {
console.log("Issue occurred")
}
},
createMsg : function(){
var content = document.createTextNode("Please give additional information."),
heading = document.createElement("h1");
heading.appendChild(content);
document.body.appendChild(heading);
},
removeMsg : function(){
}
}
document.getElementsByTagName('select')[0].onchange = function(){ menu.handleMenu(this.value)};
callback should be a string so why is it saying otherwise? Thanks for response Hi Everyone! I have a website that I'm designing where I have the need to search multiple sites at specific times. By this I mean that In some cases, we would want to search only the internet using google, or only search the site that I've created (which currently uses the jse_search.js solution), or only our company's website. I currently have four different search boxes that will search either the internet, the internal site, a separate internal site, or a third-party website, which all working fine. The problem is that the search boxes take up quite a bit of space, and the layout is becoming cumbersome. Is there a way in Javascript I could use a single search box and a drop-down list to select which method to use? The code I'm currently using is below. With the exception of the Google search function, I've modified some of the site names to general site names and paths to preserve the company's anonymity: Code in the <head> tag: Code: <script language="JavaScript1.3" type="text/javascript" src="jse_form.js"> </script> Code in the <body> tag: Code: <!--Begin Internal Site Search 1!-->

Hi experts, is it possible via Javascript to search certain websites with certain keywords without having to use specific search engines? example search only the following: 1. www.yyy.com 2. www.aaa.com 3. www.zzz.com for the keyword "Laminat" and open the sites accordingly. thx I have this code so far; PHP Code: validatePhone : function(field, caption) { phoneNumber = /^[0-9]{11}$/; if(phoneNumber.test(field.val())) { return true; } return i18n('phone', caption); }, It works fine for entering an 11 digit number. However, I want to check that the number starts with either 077, 075, 079 or 078. Also, if the field is empty then it can also be accepted. How would I do this? Thanks Hi, I'm using this site Translator Editor - LingoJam I'm trying to use the regex portion of the site (click regex on the page that link goes to) to create a substitution cipher - a translates to o, etc. so far I have Code: /a/g -> o /o/g -> u Theoretically, that'd mean when I typed in "a", it would translate to "o", and when I typed in "o", it would translate to "u". Trouble is, it doesn't know when to stop. I type in "a" and it immediately returns "u", because it substitutes the "o" that it should end up as for the "u". Any help on this matter would be appreciated. Thank you. Reply With Quote 12-29-2014, 08:34 AM #2 Philip M View Profile View Forum Posts Supreme Master coder!

You should create the cyphered text once the whole message is complete. All advice is supplied packaged by intellectual weight, and not by volume. Contents may settle slightly in transit. I am creating a userscript and trying to take the following: Arian Foster (Hou - RB) and end up just with the team name: Hou You can't remove by index (which I would be able to do), because it might be K instead of RB or NO instead of Hou. I am assuming that you use Regex and the replace function to do so, but I am struggling with understanding all Regex symbols. Can someone help me with this and explain it briefly? I would appreciate it. Should alert '' twice , instead alerts original text Code: text = 'p18=100';
text = text.replace("(^|&)p100=18.*?(&|$)","")
alert(text);
text = text.replace(/(^|&)p100=18.*?(&|$)/g,"")
alert(text);
tested regex on online tester and it should be OK. ? Hello, I have this piece of code I read from a book to remove text nodes that only have white space. Code: if (node.nodeType == 3 && ! /\S/.test(node.nodeValue)){
// code to remove the text node
}
Why should we use this: Code: ! /\S/.test(node.nodeValue) Instead of this? Code: /\s/.test(node.nodeValue) |
