I am trying to remove the "day" from every possible date occurrence on a page.
This is to make jQuery turn every date in the format of "08/22/2012" into "08/2012"
I was able to do this with this code: Replacing wildcard text using jquery
See my fiddle for more information: http://jsfiddle.net/CfZjF/223/
But it just isn't working within this table layout, regardless of what I have tried.
Another problem will be to specify the day specifically (maybe with wildcards?)-- that is the 2 numbers between the forward-slashes: /xx/, but please see the fiddle for more info.
Any ideas on how I can pull this off?
Try
str.replace(/\/\d+\//g, "/");
Or be more specific by replacing /(\d{2})\/\d{2}\/(\d{4})/g with "$1/$2" or something…
(Updated fiddle)
I think you should individually traverse the table cells instead of trying to globally muck with the entire rows HTML.
This assumes that your data is formatted as in your jsFiddle.
Updated fiddle: http://jsfiddle.net/GKrCS/
$('tr').each(function(){
$('td',this).not(':first').text(
function(){
return $(this).text().replace(/\/[0-9]+\//,'/');
});
});
Since all your dates are in the form xx/xx/xxxx, using a simple split() would always split it into an array with these values:
xx,xx,xxxx
So, something like this:
var totalDate = $("whateverYourDateSelectorMightBe");
var daysInMiddle = totalDate.val().ToString().split(",")[1];
so then you could do:
totalDate.val(totalDate.val().ToString().replace(daysInMiddle + "/",""));
Note that there are much cleaner ways to do this. I just did it this way because I think it better explains what I was trying to do.

I'm working on this WP plugin and I've been trying to get the ID of a custom post kinda thing that is declared in the body class on each page. So it goes like this;
<body class="(Bunch of other classes) ld-courses-1731-parent">
I'm trying to get the number 1731 in my JS function but the number is dynamic so I need to some regex matching with the string pattern.
Pattern: ld-courses-*INT VALUE*-parent
how can I do this with JS? Any help is much appreciated thank you so much.
You can use match if thats the only class in your body:
var classList = document.getElementsByTagName("body")[0].classList;
[...classList].forEach(function(thisClass) {
if (/ld-courses-\b/.test(thisClass)) {
var id = thisClass.match(/\d/g);
console.log(id.join(""));
}
});
<body class="another-class-before another-class-12-hasnum ld-courses-1731-parent another-class-12-hasnumaswell another-class-after">
</body>
Hi Laclogan in regards to your question yes it's possible for sure.
Correct me if i'm wrong but the number comes probably if it's changing for each post directly from the url.
The following site explains if this is the case how to get that number from the url.
https://www.sitepoint.com/get-url-parameters-with-javascript/
In addition you can use the function concat to combine the strings see this site for an example hope it helps.
https://www.w3schools.com/jsref/jsref_concat_string.asp
Could you confirm for me that the number is always present in the url or if this is not the case?
I'm having an issue trying to set an input field's value when using HTML entities in that they are coming out literally as " rather than ".
Here is the code I am using:
document.getElementById('inputSurname').setAttribute('value', 'test"""');
in which the output is test""" though I want the output to be test""".
It doesn't look like a double-encoding issue since in the source code I am seeing it the same way I have set it here.
I know I could decode the value from its HTML entity format though this is something I want to avoid if possible for security.
Any help would be much appreciated :)
Try this:
document.getElementById('inputSurname').value = 'test"""';
Or if you want to keep ":
function myFunction() {
document.getElementById('myText').value = replaceQuot('test"""');
}
function replaceQuot(string){
return string.replace('"', '""');
}
Or you can use escape characters.
document.getElementById("inputSurname").setAttribute("value", "test\"\"\"\"");
Well you could just write the new value as 'test"""'.
For other characters however, I'm going to refer you to this answer: HTML Entity Decode
I am trying to use jQuery Based text highlight plugin, it works for single word highlight but breaks when i pass array, My syntax seems to be correct as the the documentation http://bartaz.github.io/sandbox.js/jquery.highlight.html
Example: http://jsfiddle.net/YyAXP/6/
//$('#article').highlight("me");
$("#article").highlight(["me","highlight","plugin"]);
I need to pass several keywords to this function so that it highlight all of them.
Solved:
It seems script had bug which was resolved use the following fiddle with complete script for array based search highlight script source
Fiddle: http://fiddle.jshell.net/ogyyvvog/2/
It gets error when running your code
pat.toUpperCase is not a function
pat should be array, maybe you can fix it in this way?
return this.length && pat && pat.length ? this.each(function () {
for(var i=0;i<pat.length;i++)
innerHighlight(this, pat[i].toUpperCase());
}) : this;
jsfiddle
Declaration syntax is correct
$("#article").highlight(["me","highlight","plugin"]);
You just need to correctly include the plugin in your jsfiddle. Do not include tag script, use instead "External Resources" menu... check updated demo
You can use my highlighting plugin jQuiteLight, that can easily work with both arrays and also regular expressions.
// for strings
$(".element").mark("query here");
// for RegExp
$(".element").mark(new RegExp(/query reg[a-zA-Z]+/));
// for array
$(".element").mark(["string query", new RegExp(/query arr[a-z]+/)]);
I have string with html elements. There are tables with captions. I need to find table which has caption with certain text and then return this table - as a string.
What is the best way to do this with simple javascript, without any libraries ?
F.e. this is an initial string
<table border="1"><caption><strong>First</strong></caption><tbody><tr><td>...</td></tr></tbody></table><table border="1"><caption><strong>Result</strong></caption><tbody><tr><td>...</td></tr></tbody></table><table border="1"><caption><strong>Last</strong></caption><tbody><tr><td>...</td></tr></tbody></table>
I want to get this string :
<table border="1"><caption><strong>Result</strong></caption><tbody><tr><td></td></tr></tbody></table>
Any advice or algorithm how to effeciently resolve this problem ? The challenge is to resolve it with javascript without using any third-party libraries and also without converting text into xml or something similar (because some of html code is not well formatted and it causes errors).
I have not had time to completely test this, but you might be able to try using a regular expression and the match() function. Assuming your table string is in a variable called str, then something along the lines of
var res = str.match(\b<table\.\w+_</table>\b);
res will be an array of matches of strings that begin with '', which you could then check to see which string contains the caption that you need.
Hope that helps!
i'm working since hours on this issue without any success, hope to get some help here!
I use the tablesorter plugin to sort table on client side.
First of all, I set an default sort order and initalize the sorter-plugin:
var defaultSort=[[4,1]];
$("#myTable").tablesorter({sortList:defaultSort});
Which does not work (does not sort) while this works:
$("#myTable").tablesorter({sortList: [[4,1]]});
Can't see a reason for this behavior.
Later, I add columns dynamically by using getJSON. After adding a line, I have to update the tablesorter and order again (because of the new rows). For that: read the current "sortList" and try to apply this list:
$("#myTable").trigger("update");
sortOrder=$("#myTable")[0].config.sortList;
setTimeout('$("#myTable").trigger("sorton",['+sortOrder+']);',1);
But this does not work. There is no ordering.
An console.info(sortOrder) returns 4 instead of [[4,1]].
Why?
But all this code works, if the sortList is hardcoded, like:
$("#myTable").trigger("update");
setTimeout('$("#myTable").trigger("sorton",[[[4,1]]]);',1);
Thank you
try this:
var myTable = $("#myTable");
var sortOrder=myTable.trigger("update")[0].config.sortList;
setTimeout(function(){
myTable.trigger("sorton",[sortOrder]);
},1);
in your 3rd example you wrote
setTimeout('$("#myTable").trigger("sorton",['+sortOrder+']);',1);
sortOrder is having toString() called on it when you stick it in that string. That's at least one of the reasons it's not working.
