I'm trying to write asp-classic function in Javascript... but i can't seem to get it right... can someone help?
ASP:
Dim i
Dim sAscii
sAscii = ""
For i = 1 To Len(str)
sAscii = sAscii + "&#" + CStr(Asc(Mid(str, i, 1))) + ";"
Next
ascconv= sAscii
javascript:
var i;
str1 = document.getElementById('firstname').value;
var sAscii1;
i = 0;
sAscii1 = "";
for(i; i = str1.length; i++) {
sAscii1 = sAscii1 + "&#" + str1.charCodeAt(i) + ";";
}
document.getElementById('firstname').innerHTML = sAscii1;
To convert this function in javascript you have to do something like this:
var i,str1 = document.getElementById('firstname').value;
var sAscii1 = "";
for(var i=0; i < str1.length; i++) {
sAscii1 = sAscii1 + "&#" + str1.charCodeAt(i) + ";";
}
document.getElementById('firstname').value = sAscii1;//I think you made a mistake here...as you have a input variable you will get/set the value and not innerHTML
where charCodeAt is similar to Asc (converts to ascii code)
var i, sAscii = "", str = "This is a string";
for(i = 0; i < str.length; a++){
sAscii += "&#" + str[a].charCodeAt(0) + ";";
}

Is there a way to get the 'username' and 'questionid' variable's value in my send() function like how I did with inputText?
var username;
var questionid;
function renderHTML(data) {
var htmlString = "";
var username = data[0].username;
//var examid = data[1].examid;
var questionid = data[2].questionid;
for (var i = 0; i < data.length; i++) {
htmlString += "<p>" + data[i].questionid + "." + "\n" + "Question: " + data[i].question + "\n" + "<input type='text'>";
htmlString += '</p>';
}
response.insertAdjacentHTML('beforeend', htmlString);
}
function send() {
var inputText = document.querySelectorAll("input[type='text']");
var data = [];
for (var index = 0; index < inputText.length; index++) {
input = inputText[index].value;
data.push({
'text': input
});
}
console.log(data);
You do not need var before username and questionid in your renderHTML function, as they have already been defined:
var username;
var questionid;
function renderHTML(data) {
var htmlString = "";
username = data[0].username;
//var examid = data[1].examid;
questionid = data[2].questionid;
for (var i = 0; i < data.length; i++) {
htmlString += "<p>" + data[i].questionid + "." + "\n" + "Question: " + data[i].question + "\n" + "<input type='text'>";
htmlString += '</p>';
}
response.insertAdjacentHTML('beforeend', htmlString);
}
function send() {
var inputText = document.querySelectorAll("input[type='text']");
var data = [];
for (var index = 0; index < inputText.length; index++) {
input = inputText[index].value;
data.push({
'text': input
});
}
console.log(data);
Internet Explorer gives an error ')' is expected while Firefox is running this code fine. According to the Internet Explorer console the error is situated in the first line:
function HTMLtableRows (titles=[] , values=[]) {
How can I fix this problem?
function HTMLtableRows (titles=[] , values=[]) {
var i, j;
var str, strT, strM;
str = '<table class="table">';
str = str + '<tr>';
for (j = 0; j < titles.length; j++) {
str = str + '<th colspan="2"><center>' + titles[j] + '</center></th>';
}
str = str + '</tr>' + '<tr>';
for (j = 0; j < titles.length; j++) {
str = str + '<th>Tijdstip</th>' + '<th>Looptijd</th>';
}
str = str + '</tr>' + '<tr>';
for (j = 0; j < titles.length; j++) {
var a = values[j].split('\r');
strT = ''
strM = ''
for (i = 0; i < a.length; i++) {
var b = a[i].split('=');
if (b[1] != undefined) {
strT = strT + b[0];
strM = strM + b[1] + 'min';
}
if (i < a.length - 1) {
strT = strT + '<br>';
strM = strM + '<br>';
}
}
str = str + '<td>' + strT + '</td>';
str = str + '<td>' + strM + '</td>';
}
str = str + '</tr>';
str = str + '</table>';
return str;
}
IE does not support default parameters.
Just do it like this if you want
function HTMLtableRows (titles , values) {
if (!titles) titles = [];
if (!values) values = [];
console.log(titles);
console.log(values);
}
a1 = [1,2,3];
HTMLtableRows(a1, null);
HTMLtableRows({foo: "bar"}, undefined);
HTMLtableRows(2, NaN);
HTMLtableRows("not empty string", "");
HTMLtableRows(1, 0);
HTMLtableRows(true, false);
All of the following values
null
undefined
NaN
""
0
false
will become an empty array. If you don't want some of those values to be overwritten with an empty array adjust if conditions as you see fit.
Example where you allow values to remain unchanged as "", 0 and NaN:
function HTMLtableRows (titles , values) {
if (!titles) titles = [];
if(values != "" &&
values != 0 &&
!isNaN(parseInt(values))
)
values = [];
console.log(titles);
console.log(values);
}
HTMLtableRows("string", "");
HTMLtableRows(1, 0);
HTMLtableRows(7, NaN);
Thanks to alex i've solved this with the adjustments below:
function HTMLtableRows (tmpTitles , tmpValues) {
titles=[];
values=[];
titles = tmpTitles;
values = tmpValues;
//...
}
I am been trying to create a html table that is populated by objects.
The table was supposed to be selectable by row (via hover), when the row was hovered over a function ran.
The table headers are in an array:
var topTitles = ["Type","Origin","Destination","T","A","G"];
all the data are sitting inside arrays,
var Type = [];
var Origin = [];
var Destination = [];
var T = [];
var A = [];
var G = [];
I tried to modify an example piece of code, but it was very difficult to conceptualize it and place it into a programatic solution. What is an easy way to map such data directly into a interactive table.
function createTable() {
var table = document.getElementById('matrix');
var tr = addRow(table);
for (var j = 0; j < 6; j++) {
var td = addElement(tr);
td.setAttribute("class", "headers");
td.appendChild(document.createTextNode(topTitles[j]));
}
for (var i = 0; i < origins.length; i++) {
var tr = addRow(table);
var td = addElement(tr);
td.setAttribute("class", "origin");
td.appendChild(document.createTextNode(mode[i]));
for (var j = 0; j < topTitles.length; j++) {
var td = addElement(tr, 'element-' + i + '-' + j);
td.onmouseover = getRouteFunction(i,j);
td.onclick = getRouteFunction(i,j);
}
}
}
function populateTable(rows) {
for (var i = 0; i < rows.length; i++) {
for (var j = 0; j < rows[i].elements.length; j++) {
var distance = rows[i].elements[j].distance.text;
var duration = rows[i].elements[j].duration.text;
var td = document.getElementById('element-' + i + '-' + j);
td.innerHTML = origins[i] + "<br/>" + destinations[j];
}
}
}
if (highlightedCell) {
highlightedCell.style.backgroundColor="#ffffff";
}
highlightedCell = document.getElementById('element-' + i + '-' + j);
highlightedCell.style.backgroundColor="#e0ffff";
showValues();
}
This is probably the easiest way I could think of building the table without changing your data structure and make it very clear where all the data is coming from. It is defiantly not the best code, but it should work for your situation.
CodePen
var topTitles = ["Type","Origin","Destination","T","A","G"];
var Type = ["Type1", "type2", "type3"];
var Origin = ["Origin1", "origin2", "origin3"];
var Destination = ["Destination1", "Destination2", "dest3"];
var T = ["t1", "t2","T3"];
var A = ["steaksauce", "a2", "a3"];
var G = ["G1", "G2", "G3"];
var appendString = [];
for(var i =0; i < topTitles.length; i++){
if(!i){
appendString.push("<tr><td>" + topTitles[i] + "</td>");
}
else if(i === topTitles.length -1){
appendString.push("<td>" + topTitles[i] + "</td></tr>");
}
else{
appendString.push("<td>" + topTitles[i] + "</td>");
}
}
for(var i =0; i < Type.length; i++){
appendString.push("<tr><td>" + Type[i] + "</td><td>" + Origin[i] + "</td><td>" + Destination[i] + "</td><td>" + T[i] + "</td><td>" + A[i] + "</td><td>" + G[i] + "</td></tr>");
}
var table = document.getElementById('table');
table.innerHTML = appendString.join('');
In my table 1st column has a tags with href's and 3rd column has some text. So, I want to save all href's into an array where their respective 3rd column matches some string and use it for later purpose. I had tried the following code nothing seems wrong to me, can some one assist me with this.
function findimagelinks(){
var rows = jQuery(".sortable tr.even").length + jQuery(".sortable tr.odd").length;
var imglinks = [];
for (i=0; i<rows; i++){
var conditionvalue =jQuery(".sortable tr:eq(i+1) td:eq(3)").text();
if(conditionvalue == "some string"){
imglinks[i] = jQuery(".sortable tr:eq(i+1) td:eq(0) a").attr('href');
}
}
console.log(imglinks);
}
findimagelinks();
String concatenation is not right!
var conditionvalue = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();
// ------------------------------------------^
imglinks[i] = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(0) a").attr('href');
// -----------------------------------^
Updated Snippet
function findimagelinks(){
var rows = jQuery(".sortable tr.even").length + jQuery(".sortable tr.odd").length;
var imglinks = [];
for (i = 0; i < rows; i++) {
var conditionvalue = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();
if (conditionvalue == "some string") {
imglinks[i] = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(0) a").attr('href');
}
}
console.log(imglinks);
}
findimagelinks();
Your selector is wrong. Properly concatenate the strings like this
var conditionvalue = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();
Then your code will look like,
for (i = 0; i < rows; i++) {
var conditionvalue = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(3)").text();
if (conditionvalue == "some string") {
imglinks[i] = jQuery(".sortable tr:eq(" + (i + 1) + ") td:eq(0) a").attr('href');
}
}
i have implemented this code to display xml in html using javascript
current output
Need something like
Here is my code
function parseXML(R, s) {
var C = R.childNodes;
var str = '';
for (var i = 0; i < C.length; i++) {
var n = C[i];
var f = false;
if (n.nodeType !== 3) {
str += '<br><<span class="nn">' + n.nodeName + '</span>>';
if (n.hasChildNodes()) {
f = true;
str += parseXML(n, s++);
}
str += '</<span class="nn">' + n.nodeName + '</span>>';
} else {
str += '<span class="nv">' + n.nodeValue + '</span>';
}
if (f) {
str += '<br>';
}
}
var str = str.replace(/(<br>)+/g, '<br>');
return str;
}
how i call this
R : xml object
s : initial 0 (i am passing this so that i can display xml as hirarchical view)
Output in second
- is not required
i have post second out as it can be seen while opening xml document in firefox
please ask if any doubt
I solved it myself.
Updated code with the solution
var pre = 0;
function parseXML(R, s) {
var C = R.childNodes;
var str = '';
for (var i = 0; i < C.length; i++) {
var n = C[i];
if (n.nodeType !== 3) {
str += '<br>' + gs(s) + '<b><</b><span class="nn">' + n.nodeName + '</span><b>></b>';
if (n.hasChildNodes()) {
str += parseXML(n, s + 1);
}
if (pre !== 3) {
str += '<br>' + gs(s);
}
str += '<b><</b>/<span class="nn">' + n.nodeName + '</span><b>></b>';
} else {
str += '<span class="nv">' + n.nodeValue + '</span>';
}
pre = n.nodeType;
}
return str;
}
