Let's say I have some sentences in Google Docs. Just one sentences as an example:
"My house is on fire"
I actually changed the background color so that every verb is red and every noun blue.
Now I want to make a list with all the verbs and another one with the nouns. Unfortunately getBackgroundColor() only seems to work with paragraphs and not with single words.
My idea was, to do something like this (I didn't yet have the time to think about how to do the loop, but that's not the point here anyway):
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();
var paragraphs = body.getParagraphs();
var colorVar = paragraphs[0].getText().match(/\w+/).getBackgroundColor(); // The regEx matches the first word. Next I want to get the background color.
Logger.log(colorVar);
}
The error message I get goes something like this:
"The function getBackgroundColor in the text object couldn't be found"
Thx for any help, or hints or comments!
You want to retrieve the text from a paragraph.
You want to retrieve each word and the background color of each word from the retrieved the text.
In this case, the color is the background color which is not getForegroundColor().
You want to achieve this using Google Apps Script.
If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.
At first, the reason of your error is that getBackgroundColor() is the method of Class Text. In your script, getBackgroundColor() is used for the string value. By this, the error occurs.
In this answer, for achieving your goal, each character of the text retrieved from the paragraph is scanned, and each word and the background color of each word can be retrieved.
Sample script:
function myFunction() {
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();
var paragraphs = body.getParagraphs();
var textObj = paragraphs[0].editAsText();
var text = textObj.getText();
var res = [];
var temp = "";
for (var i = 0; i < text.length; i++) {
var c = text[i];
if (c != " ") {
temp += c;
} else {
if (temp != "") res.push({text: temp, color: textObj.getBackgroundColor(i - 1)});
temp = "";
}
}
Logger.log(res) // result
}
When you run the script, the text of 1st paragraph is parsed. And you can see the result with res as an object.
In this sample script, the 1st paragraph is used as a test case. So if you want to retrieve the value from other paragraph, please modify the script.

The code is used in a HTML document, where when you press a button the first word in every sentence gets marked in bold
This is my code:
var i = 0;
while(i < restOftext.length) {
if (text[i] === ".") {
var space = text.indexOf(" ", i + 2);
var tekststykke = text.slice(i + 2, space);
var text = text.slice(0, i) + "<b>" + tekststykke + "</b>" + text.slice(i + (tekststykke.length + 2));
var period = text.replace(/<b>/g, ". <b>");
var text2 = "<b>" + firstWord + "</b>" + period.slice(space1);
i++
}
}
document.getElementById("firstWordBold").innerHTML = text2;
}
It's in the first part of the code under function firstWordBold(); where it says there is an error with
var space1 = text.indexOf(" ");
Looks like you're missing a closing quote on your string, at least in the example you provided in the question.
Your problem is the scope of the text variable. In firstWordBold change every text to this.text, except the last two where you re-define text
Also, if you want to apply bold to the first word this is easier...
document.getElementById('test-div-2').innerHTML = '<b>' + firstWord + '</b>' + restOftext;
It now works for me, with no errors and it applies bold to the first word.
Here's how the function ended up,
function firstWordBold() {
console.log('bolding!');
var space1 = this.text.indexOf(' ');
var firstWord = this.text.slice(0, space1);
var restOftext = this.text.slice(space1);
document.getElementById('test-div-2').innerHTML = '<b>' + firstWord + '</b>' + restOftext;
}
To make every first word bold, try this...
function firstWordBold() {
let newHTML = '';
const sentences = this.text.split('.');
for (let sentence of sentences) {
sentence = sentence.trim();
var space1 = sentence.indexOf(' ');
var firstWord = sentence.slice(0, space1);
var restOftext = sentence.slice(space1);
newHTML += '<b>' + firstWord + '</b>' + restOftext + ' ';
}
document.getElementById('test-div-2').innerHTML = newHTML;
}
One last edit, I didn't notice you had sentences ending with anything other that a period before. To split on multiple delimiters use a regex, like so,
const sentences = this.text.split(/(?<=[.?!])\s/);
I was trying to make something where you can type a string, and the js only shows the objects containing this string. For example, I type Address1 and it searches the address value of each one then shows it (here: it would be Name1). Here is my code https://jsfiddle.net/76e40vqg/11/
HTML
<input>
<div id="output"></div>
JS
var data = [{"image":"http://www.w3schools.com/css/img_fjords.jpg","name":"Name1","address":"Address1","rate":"4.4"},
{"image":"http://shushi168.com/data/out/114/38247214-image.png","name":"Name2","address":"Address2","rate":"3.3"},
{"image":"http://www.menucool.com/slider/jsImgSlider/images/image-slider-2.jpg","name":"Name3","address":"Address3","rate":"3.3"}
];
var restoName = [], restoAddress = [], restoRate = [], restoImage= [];
for(i = 0; i < data.length; i++){
restoName.push(data[i].name);
restoAddress.push(data[i].address);
restoRate.push(data[i].rate);
restoImage.push(data[i].image);
}
for(i = 0; i < restoName.length; i++){
document.getElementById('output').innerHTML += "Image : <a href='" + restoImage[i] + "'><div class='thumb' style='background-image:" + 'url("' + restoImage[i] + '");' + "'></div></a><br>" + "Name : " + restoName[i] + "<br>" + "Address : " + restoAddress[i] + "<br>" + "Rate : " + restoRate[i] + "<br>" + i + "<br><hr>";
}
I really tried many things but nothing is working, this is why I am asking here...
Don't store the details as separate arrays. Instead, use a structure similar to the data object returned.
for(i = 0; i < data.length; i++){
if (data[i].address.indexOf(searchedAddress) !== -1) { // Get searchedAddress from user
document.getElementById("output").innerHTML += data[i].name;
}
}

I'm trying to use my text input as a string variable and use that variable as a part of a URL to pull up JSON data but I can't seem to get it to work properly.
I don't know if I'm setting the variables incorrectly but any help would be appreciated. Thank you!
$(document).ready(function() {
var p = document.querySelector('p');
var input = document.getElementById('search').value;
$("#go").click(function() {
if (input === '') {
p.style.backgroundColor = 'transparent';
p.classList.add = 'hide';
p.innerHTML = '';
} else {
$.getJSON("https://en.wikipedia.org/w/api.php?action=opensearch&datatype=json&limit=5&search=" + input + "&callback=?", function(data) {
p.innerHTML = "<br> Click the links below";
p.classList.remove('hide');
var i = 0
for (i; i < 5; i++){
if (data[3][i] !== undefined){
p.innerHTML += '<h2> <a href ="' + data[3][i] + '" target = "_blank">' + data[1][i] + '<br>' + '<h3>' + data[2][i] + '</h3>' + '</h2>'
} else {
p.innerHTML = ' <h2> No matching result </h2>';
}
}
});
}
});
});
At the time you assign the variable value, it is empty because it is run when the site is loaded and there is probably no text in the search box yet. You want the content at the time #go is clicked, so just assign it inside the click event handler:
$(document).ready(function() {
var p = document.querySelector('p');
// the text field value is empty at this point
$("#go").click(function() {
// this is run when user clicks #go
var input = document.getElementById('search').value;
if (input === '') {
p.style.backgroundColor = 'transparent';
p.classList.add = 'hide';
p.innerHTML = '';
}
else {
// encode user input
$.getJSON("https://en.wikipedia.org/w/api.php?action=opensearch&datatype=json&limit=5&search=" + encodeURIComponent(input) + "&callback=?", function(data) {
p.innerHTML = "<br> Click the links below";
p.classList.remove('hide');
var i = 0
for (i; i < 5; i++){
if (data[3][i] !== undefined){
p.innerHTML += '<h2> <a href ="' + data[3][i] + '" target = "_blank">' + data[1][i] + '<br>' + '<h3>' + data[2][i] + '</h3>' + '</h2>'
}
else {
p.innerHTML = ' <h2> No matching result </h2>';
}
}
});
}
});
});
Additionally, you should always encode user input if you include it in a URI. Otherwise you'll experience unexpected behaviour when using any non alphanumerical character (including whitespace) in the search box. For a more detailed explanation of how and why, see the documentation.
The embedded "\n" characters in the following code does NOT produce line breaks in the generated string. What am I to do??? :-)
/* Load array into DOM */
var directory = document.getElementById ("directory");
directory.innerHTML = "";
var numberOfHouses = house.length;
for (i = 0; i < numberOfHouses; i++) {
var houseNode = document.createElement('span');
var text = (house[i][0] + "\n" + house[i][1] + "\n" + house[i][2] + "\n" + house[i][3] + "\n " + house[i][4] + "\n" + house[i][5] + "\n" + house[i][6] + "\n" + house[i][7] + "\n" + house[i][8] + "\n\n");
var houseText = document.createTextNode(text);
houseNode.appendChild(houseText);
directory.appendChild(houseNode);
}
That's because a linefeed in a text node does not render as a linefeed.
If you want a linefeed on a web page, you need to use CSS such as white-space: pre-line; to make them count, or add a <br> element
You need to be using <br> to make the new lines. You are creating the string in javascript, but it is being interpreted in HTML.
var directory = document.getElementById ("directory");
directory.innerHTML = "";
var numberOfHouses = house.length;
for (row = 0; row < numberOfHouses; row++) {
var houseNode = document.createElement('span');
for (column = 0; column < 9; column++) {
var text = (house[row][column]);
var houseText = document.createTextNode(text);
houseNode.appendChild(houseText);
directory.appendChild(houseNode);
var brNode = document.createElement ('br');
houseNode.appendChild(brNode);
}
var pNode = document.createElement('p');
directory.appendChild(pNode);
}
// Fixed!
Basically, I'm using JavaScript to dynamically generate a form that allows from multiple entries within a single submission. Here's the code I'm using for that:
function addEvent()
{
var ni = document.getElementById('myDiv');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value - 1) + 2;
numi.value = num;
var divIdName = 'my' + num + 'Div';
var newdiv = document.createElement('div');
newdiv.setAttribute('id', divIdName);
newdiv.innerHTML = '<table id="style" style="background-color: #ffffff;"><tr><td colspan="2">Entry ' + num + '<hr \/><\/td><\/tr><tr><td><label>Item 1: <\/td><td><input name="item1_' + num + '" value="" type="text" id="item1" \/><\/label><\/td><\/tr><tr><td><label>Item 2: <\/td><td><input name="item2_' + num + '" type="text" id="item2" \/><\/label><\/td><\/tr><tr><td><label>Item 3: <\/td><td><input type="text" name="item3_' + num + '" id="item3" \/><\/label><\/td><\/tr><tr><td><label>Item 4: <\/td><td><select name="item4_' + num + '" id="item4"><option value="---">---<\/option><option value="opt_1">1<\/option><option value="opt_2">2<\/option><option value="opt_3">3<\/option><option value="opt_4">4<\/option><\/select><\/label><\/td><\/tr><\/table>';
ni.appendChild(newdiv);
}
This works just fine, generating the entries fields I need. Using console in-browser, I've even verified all the names are correct. The issue is that I need to then take the selections and generate output. I've tried several methods, but everything resulted in null values.
function generateVideo()
{
var entries = document.getElementById('theValue').value;
var item1 = {};
var item2 = {};
var item3 = {};
var item4 = {};
for(i = 1; i <= entries; i++)
{
item1[i - 1] = document.getElementById('item1_' + i);
item2[i - 1] = document.getElementById('item2_' + i);
item3[i - 1] = document.getElementById('item3_' + i);
item4[i - 1] = document.getElementById('item4_' + i);
}
var code = 'Copy code and paste it into Notepad<br \/>"Save as" filename.html<br \/><textarea name="" cols="45" rows="34">header template\n';
for(i = 0; i < entries; i++)
{
if(i != (entries - 1))
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"],\n';
}
else
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"]\n';
}
}
code = code + 'footer template<\/textarea>';
var result = document.getElementById("result");
result.innerHTML = code;
}
The output is as follows:
Copy code and paste it into Notepad<br />"Save as" CourseName_Unit_Chapter.html<br /><textarea name="" cols="45" rows="34">header template
["null", "null", "null", "null"]
footer template</textarea>
Now, certain fields can be null, that's fine (I'll do form validation after I get it working), but I'm getting null for every field regardless of what is entered.
I, originally, had the .value on the getElementByIds, but that only results in the script not running when the entries variable is greater than 0 (default), which is why I tried removing them.
function generateVideo()
{
var entries = document.getElementById('theValue').value;
var item1 = {};
var item2 = {};
var item3 = {};
var item4 = {};
for(i = 1; i <= entries; i++)
{
item1[i - 1] = document.getElementById('item1_' + i).value;
item2[i - 1] = document.getElementById('item2_' + i).value;
item3[i - 1] = document.getElementById('item3_' + i).value;
item4[i - 1] = document.getElementById('item4_' + i).value;
}
var code = 'Copy code and paste it into Notepad<br \/>"Save as" filename.html<br \/><textarea name="" cols="45" rows="34">header template\n';
for(i = 0; i < entries; i++)
{
if(i != (entries - 1))
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"],\n';
}
else
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"]\n';
}
}
code = code + 'footer template<\/textarea>';
var result = document.getElementById("result");
result.innerHTML = code;
}
I've also tried variations of multidimensional arrays, instead of four arrays, but got the same results.
The output, as indicated by the removal of the .value on the getElementByIds, is good. Basically, there is something wrong with my attempts to populate the arrays using the dynamically generated forms.
I suspect that the issue with the declaration of the element ID, but I'm not sure how else to declare it. This style of scripting is not my norm. ^^'
Anyone have any ideas on how to fix the for loop to generate the array?
replace all occurences of
itemN[i]
with
itemN[i].value
if that doesnt work add
console.log( itemN[i] )
and see what it outputs
