  • Change value of textarea when hovering link

    - by hellfyr
    I would like to change the value of a textarea when hovering over a link. I am not very proficient at javascript and do not quite understand the intricacies of 'this.' and 'document.' etc.. Currently I have a textarea 'info' that on page load is unpopulated and two links that should change its value. I can not seem to get it to work.. <textarea name="info"></textarea> <a href="foo.com" onmouseover="document.info.value='foo.com is a great site'">Foo.com</a> <a href="bar.com" onmouseover="document.info.value='bar.com is a terrible site'">Bar.com</a> I'm sure there is a way to accomplish what I need to do but I can't find it. Thanks in advance.

  • PHP: Return string between two characters

    - by Nic Hubbard
    I am wanting to use "keywords" within a large string. These keywords start and end using *my_keyword* and are user defined. How, within a large string, can I search and find what is between the two * characters and return each instance? The reason it might change it, that parts of the keywords can be user defined, such as *page_date_Y* which might show the year in which the page was created. So, again, I just need to do a search and return what is between those * characters. Is this possible, or is there a better way of doing this if I don't know the "keyword" length or what i might be?

    - by Newbie
    In the app.config file if I use <add key = "FileDelimeter" value ="&#2c;"/> as unicode for COMMA, it is throwing error Invalid character in a decimal number 'c' For SPACE, <add key = "FileDelimeter" value ="&#20;"/> the error is Character'', hex value 0*14 is illegal in xml while <add key = "FileDelimeter" value ="&#09;"/> for "\t" worked.

  • Change selected value of drop down list with jQuery

    - by Phairoh
    I have a drop down list with known values. What I'm trying to do is set the drop down list to a particular value that I know exists using jQuery. Using regular JavaScript, I would do something like: ddl = document.getElementById("ID of element goes here"); ddl.value = 2; // 2 being the value I want to set it to. However, I need to do this with jQuery because I'm using a CSS class for my selector (stupid ASP.NET client ids...). Here are a few things I've tried: $("._statusDDL").val(2); // doesn't find 2 as a value $("._statusDDL").children("option").val(2) // also failed. How can I do it with jQuery?

  • Recursively determine average value

    - by theva
    I have to calculate an average value of my simulation. The simulation is ongoing and I want (for each iteration) to print the current average value. How do I do that? I tried the code below (in the loop), but I do not think that the right value is calculated... int average = 0; int newValue; // Continuously updated value. if(average == 0) { average = newValue; } average = (average + newValue)/2; I also taught about store each newValue in an array and for each iteration summarize the whole array and do the calculation. However, I don't think that's a good solution, because the loop is an infinity loop so I can't really determine the size of the array. There is also a possibility that I am thinking too much and that the code above is actually correct, but I don't think so...

  • Both sql LAST_INSERT_ID() and PHP insert_id return 0

    - by jakubplus
    I've been searching google a lot for this issue and really found nothing. People just keep copying MySQL documentation on last_insert_id and nothing else. I've got an issue regarding last_insert_id, because for both situations (php & sql) it returns 0. YES: I've set a PRIMARY & UNIQUE field with AUTO_INCREMENT value YES: i've done some inserting before NO: Making double query with INSERT AND SELECT LAST... doesn't work. I've created a class Db for maintaining connection & query: class Db { public function connect() { $db = new mysqli('','','','',''); ... return $db; } public function insert() { $this->connect()->query("INSERT INTO bla bla..."); return $this->connect()->insert_id; } } And it doesn't work.
