I am having a bit of trouble understanding understanding this function. Specifically, I am having a bit of trouble comprehending what the "-" does. Is it simply the opposite of using +?The code:
i currently have a problem which i cant resolve and i cant seem to find a solution (i actually not sure what to look for). My jquery level is medium-low and im trying to take it to a higher level right now.
I have a var which holds a href value. However i only need part of the string.
I am having troubles manipulating DOM elements inside a variable. I have the following code:
var $content = pages[pageId].page; $('.widget_inline'
[Code]....
Inside this html string there are multiple id's that I have to change. The .each finds the rightelements and the manipulation seems to work when I do a console.log onwidgetElement.However the actual $content remains unchanged. I probably made a very obvious mistake but I can't find it.
I am trying to search an array for a string and then if it is found alert it. I have found examples of how to iterate the array and how to use .IndexOf to return a true false statement as to whether the array includes the string, but i don't know what to do after that and how to display the string if its found.
I'm looking for a way to grab a number from a string, although this number is not at either end of the string.
Here is the string in question: var el = "v4Function_Name('argument3')"
Here is a substring that returns the number ( the 3 ) successfully... var number = el.substring(el.lastIndexOf("ent")+3,el.length-2);
Seems very ineffecient to do it this way, and better to find a lean elegant way using replace(); How does one go about getting a value inside of a string with regular expressions? .. or is there a better way?
Here are a couple of the many expressions I have failed with...
var pat = /^[^ent][0-9]*$"/; var pat = /v4Function_Name('argument([^0-9]+)'/; var number = el.replace(pat,"");
I am working on a project with asp.net and vb.net language system.Now I made a table on the asp file, and before clicking on a button "update", by JavaScript, I would like to get all the string data written in the text boxes each placed inside a cell of the table.Now, I wrote the following codes;
function getData(){ var tblData = new Array(); var table = document.getElementById("<%=tblA.ClientID%>");
I've been searching for about 3 days on this topic. I'm trying to get a template field inside of an ASP.Net detailsview control inside of an ajax updatepanel to work with the jquery datepicker. Very frustrating! I'm using VB with VS 2010. I can get the datepicker to work fine with a simple text box inside of an update panel but when I put it inside of a detailsview control it stops working.
I need a simple, quick and efficient way to logically branch if I find a string is contained in another string in jquery Most other languages this can be resolved in one or two lines and it would be readable.
var obj = {}; with(obj) { var x = 10; } print(x); print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the value 10. But it's not the case, because variable declarations are placed at the start of function code (or global code), so the previous code is equivalent with:
var obj; var x; obj = {}; with(obj) { x = 10; } print(x); print(obj.x);
You can clearly see now that x is placed in the outer context. But consider the next:
var obj = {}; with(obj) { eval("var x = 10;"); } print(x); print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it gives the same output as the previous code. I tested it with spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could not find anything that describes that behaviour. Code:
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.callback should be a string so why is it saying otherwise?
I have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() { if (Selection=="Select State") alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.
<script type="text/javascript"> var str="Welcome to Microsoft! Microsoft Microsoft"; var stringToBeFound = 'Microsoft' var ReplaceString = 'site' document.write(str.replace(stringToBeFound , ReplaceString )); </script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
