Essentially what I am trying to do is to run a a function that adds up different variables and sets a new one its pretty simple:
addup: function () {
this.homeScore1 = this.m1g1h + this.m1g2h + this.m1g3h + this.m1g4h + this.m2g1h + this.m2g2h + this.m2g3h + this.m2g4h;
this.awayScore1 = this.m1g1a + this.m1g2a + this.m1g3a + this.m1g4a + this.m2g1a + this.m2g2a + this.m2g3a + this.m2g4a;
this.homeScore2 = this.m3g1h + this.m3g2h + this.m3g3h + this.m3g4h + this.m4g1h + this.m4g2h + this.m4g3h + this.m4g4h;
this.awayScore2 = this.m3g1a + this.m3g2a + this.m3g3a + this.m3g4a + this.m4g1a + this.m4g2a + this.m4g3a + this.m4g4a;
this.hdoubles = this.m5g1h + this.m5g2h + this.m5g3h + this.m5g4h;
this.adoubles = this.m5g1a + this.m5g2a + this.m5g3a + this.m5g4a;
alert(this.m1g1h);
//total handicap is set here
this.hhandicap = this.singlesHHandicap + this.doublesHHandicap;
this.ahandicap = this.singlesAHandicap + this.doublesAHandicap;
//total score is calculated here
this.homescore = this.homeScore1 + this.homeScore2 + this.hdoubles + this.hhandicap;
this.awayscore = this.awayScore1 + this.awayScore2 + this.adoubles +this.ahandicap;
},
the value of this.m1g1h for example is set in a function called this.updatesSinglesScores(); that is run on page creation, It calls my databse and assignes the values returned to some vue variables:
created: function () {
this.updatesSinglesScores();
this.updateDoublesScores();
},
afterwards I call the addup function on mounted:
mounted: function () {
this.addup();
}
So the problem I am having is that the variable this.homeScore1 for example, that is being displayed in the html of the page does not chnages it remains to 0. Upon further inspection with the alert in the addup function I learned that this.m1g1h remains 0, even though it should be another value. Furthermore if I run the addup function with a button everything works fine. So could some one explain to me why this.m1g1h remains 0? also why does the addup function work when called from a button?

Trying to get this string I have in JavaScript to appear in a paragraph in my HTML page by mousing over another paragraph.
function showInfo()
{
for (i = 0; i < object2; i = i + 1)
{
var myParagraph = "Name of Business: " + info.insurance[i].name + "\nState: " + info.insurance[i].state + "\nDiscount: " + info.insurance[i].discount + "\n" + "(" + i + 1 + "of" + object2 + ")"
}
}
myDiscount.addEventListener("mouseover", showInfo, false);
myDiscount.addEventListener("mouseout", showInfo, false);
<p id="discount">Show me the discounts!</p>
<p id="myP"></p>
If you want to show the next element of the info.insurance array each time you mouse over the paragraph, you shouldn't be using a for loop. That will do it all at once, not once for each mouseover. You need to put the counter in a global variable, and just increment it each time you call the function.
Yuo show it by assigning it to the innerHTML of the paragraph. You also need to use <br> rather than \n to make newlines (unless the style of the paragraph is pre).
var insurance_counter = 0;
function showInfo() {
var myParagraph = "Name of Business: " + info.insurance[insurance_counter].name + "<br>State: " + info.insurance[insurance_counter].state + "<br>Discount: " + info.insurance[insurance_counter].discount + "<br>(" + (insurance_counter + 1) + "of" + object2 + ")";
document.getElementById("myP").innerHTML = myParagraph;
insurance_counter++;
if (insurance_counter >= object2) { // wrap around when limit reached
insurance_counter = 0;
}
}
This function is designed to report and increment the total (counter) for each specific obstacle.
function warningMaker( obstacle ){
var count = 0;
return function ( number, location ) {
count++;
alert("Beware! There have been " +
obstacle +
" sightings in the Cove today!\n" +
number +
" " +
obstacle +
"(s) spotted at the " +
location +
"!\nThis is Alert #" + count + " today for " + obstacle + " danger."
);
};
}
Now if I call the function by saying for example,
warningMaker("obstacleName1")(2,"locationName"); ===counter 1
warningMaker("obstacleName1")(2,"locationName"); ===counter still 1
But if I call it this way,
var obstacle1Maker = warningMaker("obstacleName1");
var obstacle2Maker = warningMaker("obstacleName2");
obstacle1Maker(2,"MiddleEarth");
obstacle1Maker(2,"Hogwarts");
obstacle2Maker(3,"Narnia");
The counter is incremented for every specific obstacle, how is this possible? I'm new to Javascript and I'm trying to grasp the concepts behind things like this.
Two different closures hold two different counters. You want sth like this:
var obstacles={};
function warningMaker( obstacle ){
var obstacles[obstacle] = obstacles[obstacle]||0;
return function ( number, location ) {
obstacles[obstacle]++;
alert("Beware! There have been " +
obstacle +
" sightings in the Cove today!\n" +
number +
" " +
obstacle +
"(s) spotted at the " +
location +
"!\nThis is Alert #" + obstacles[obstacle] + " today for " + obstacle + " danger."
);
};
}
Im storing all counts in a global object. Its therefore not dependent on closures etc...
Why your code doesnt work as expected:
warningMaker("obstacleName1");
This assembles a new function context ( function + closure ). It happens when you move a function out of its scope ( variable surrounding ). The function can still access it, as its bound to them ( called closure). So if you call that twice, you will create two different contexts with two different count variables...
I am trying to create a webapp that will display information and update it when a JSON file is updated. My current code only updates when both the JSON file are updated and the page is refreshed. The key is not to have the page refreshed. Here is my current code
<script>
$.getJSON('package.json', function (data) {
for (var i in data) {
var username = data[i].username;
var value = data[i].value;
var tokens = data[i].tokens;
$("#playerlist").append('<tr><td>-' + username + ' has deposited $' + value + ' in ' + tokens + ' tokens' + '</td></tr>');
}
});
</script>
Any help is very appreciated. Thanks!
By using SetInterval we can update the UI in some timeinterval.
function refreshContent()
{
$.getJSON('package.json', function (data) {
for (var i in data) {
var username = data[i].username;
var value = data[i].value;
var tokens = data[i].tokens;
$("#playerlist").append('<tr><td>-' + username + ' has deposited $' + value + ' in ' + tokens + ' tokens' + '</td></tr>');
}
setTimeOut(refreshContent, 1000) /// again wait for 1 sec and do refresh
});
}
setTimeOut(refreshContent, 1000) \\\this will update in every 1 sec.
Basically this is supposed to find the values in specific columns of the row and add them together to get a total and place that total in the cell specified. It is not working for some reason.
function rating(Irange,Q,Y,AG,AO,AW,BE,BM) {
var sheet = SpreadsheetApp.getActiveSheet();
var values = sheet.getDataRange().getValues();
var range = sheet.getRange(Irange);
var row = Irange.getRow();
var total = Number(values[row][8]) +
Number(values[row][9]) +
Number(values[row][10]) +
Number(values[row][11]) +
Number(values[row][16]) +
Number(values[row][17]) +
Number(values[row][18]) +
Number(values[row][19]) +
Number(values[row][24]) +
Number(values[row][25]) +
Number(values[row][26]) +
Number(values[row][27]) +
Number(values[row][32]) +
Number(values[row][33]) +
Number(values[row][34]) +
Number(values[row][35]) +
Number(values[row][40]) +
Number(values[row][41]) +
Number(values[row][42]) +
Number(values[row][43]) +
Number(values[row][48]) +
Number(values[row][49]) +
Number(values[row][50]) +
Number(values[row][51]) +
Number(values[row][56]) +
Number(values[row][57]) +
Number(values[row][58]) +
Number(values[row][59]) +
Number(values[row][64]) +
Number(values[row][65]) +
Number(values[row][66]) +
Number(values[row][67]);
return total;
}
It looks odd that you're doing
var range = sheet.getRange(Irange);
...and then not using that range for anything. Instead, on the next line, you have:
var row = Irange.getRow();
I haven't done virtually anything with Google Docs Spreadsheets, but perhaps that should be range.getRow() (no I), since Range objects have a getRow method. (Naturally I have no idea what your Irange argument is, but it looks like you're using it as a string when calling getRange(a1Notation)).
I've been working on a script which collates the scores for a list of user from a website. One problem is though, I'm trying to load the next page in the while loop, but the function is not being loaded...
casper.then(function () {
var fs = require('fs');
json = require('usernames.json');
var length = json.username.length;
leaderboard = {};
for (var ii = 0; ii < length; ii++) {
var currentName = json.username[ii];
this.thenOpen("http://www.url.com?ul=" + currentName + "&sortdir=desc&sort=lastfound", function (id) {
return function () {
this.capture("Screenshots/" + json.username[id] + ".png");
if (!casper.exists(x("//*[contains(text(), 'That username does not exist in the system')]"))) {
if (casper.exists(x('//*[#id="ctl00_ContentBody_ResultsPanel"]/table[2]'))) {
this.thenEvaluate(tgsagc.tagNextLink);
tgsagc.cacheCount = 0;
tgsagc.
continue = true;
this.echo("------------ " + json.username[id] + " ------------");
while (tgsagc.
continue) {
this.then(function () {
this.evaluate(tgsagc.tagNextLink);
var findDates, pageNumber;
pageNumber = this.evaluate(tgsagc.pageNumber);
findDates = this.evaluate(tgsagc.getFindDates);
this.echo("Found " + findDates.length + " on page " + pageNumber);
tgsagc.checkFinds(findDates);
this.echo(tgsagc.cacheCount + " Caches for " + json.username[id]);
this.echo("Continue? " + tgsagc["continue"]);
this.click("#tgsagc-link-next");
});
}
leaderboard[json.username[id]] = tgsagc.cacheCount;
console.log("Final Count: " + leaderboard[json.username[id]]);
console.log(JSON.stringify(leaderboard));
} else {
this.echo("------------ " + json.username[id] + " ------------");
this.echo("0 Caches Found");
leaderboard[json.username[id]] = 0;
console.log(JSON.stringify(leaderboard));
}
} else {
this.echo("------------ " + json.username[id] + " ------------");
this.echo("No User found with that Username");
leaderboard[json.username[id]] = null;
console.log(JSON.stringify(leaderboard));
}
});
while (tgsagc.continue) {
this.then(function(){
this.evaluate(tgsagc.tagNextLink);
var findDates, pageNumber;
pageNumber = this.evaluate(tgsagc.pageNumber);
findDates = this.evaluate(tgsagc.getFindDates);
this.echo("Found " + findDates.length + " on page " + pageNumber);
tgsagc.checkFinds(findDates);
this.echo(tgsagc.cacheCount + " Caches for " + json.username[id]);
this.echo("Continue? " + tgsagc["continue"]);
return this.click("#tgsagc-link-next");
});
}
Ok, looking at this code I can suggest a couple of changes you should make:
I don't think you should be calling return from within your function within then(). This maybe terminating the function prematurely. Looking at the casperjs documentation, the examples don't return anything either.
Within your while loop, what sets "tgsagc.continue" to false?
Don't use "continue" as a variable name. It is a reserved word in Javascript used for terminating an iteration of a loop. In your case this shouldn't be a problem, but its bad practice anyhow.
Don't continually re-define the method within your call to the then() function. Refactor your code so that it is defined once elsewhere.
We ended up having to scope the function, so it loads the next page in the loop.
This is mainly because CasperJS is not designed to calculate scores, and it tries to asynchronously do the calculation, missing the required functions
