Wrap around search with window.find() doesn't work


Wrap around search with window.find() doesn't work



I'm trying to use the window.config() function to trigger search with a button. However, the wrap around boolean is set on true but doesn't actually work...



Syntax : window.find(aString, aCaseSensitive, aBackwards, aWrapAround, aWholeWord, aSearchInFrames, aShowDialog);


window.find(aString, aCaseSensitive, aBackwards, aWrapAround, aWholeWord, aSearchInFrames, aShowDialog);



My code : window.find(text, false, false, true, false, false, false);


window.find(text, false, false, true, false, false, false);

Do you have some ideas ?
Thank you :)



EDIT : I finally found the solution on this website : http://www.javascripter.net/faq/searchin.htm



Exactly what I needed :)

You are missing to call the findString(text); function. Call that with a text parameter and it will work:


findString(text);


text




findString = function findText(text) {
  window.find(text, false, false, true, false, false, false);

// syntax : window.find(aString, aCaseSensitive, aBackwards, aWrapAround, aWholeWord, aSearchInFrames, aShowDialog);
}

findString('minim veniam');


#container {
width:300px;
height:300px;
overflow:scroll
}

<button type="button" onClick='findString("lorem")'>Search for Lorem</button>





Thank you for the answer, but I do call the function with the onClick attribute of my button : <button type="button" onClick='findString("lorem")'>Search for Lorem</button>...

@Anatole so what is the issue then?

When the last item is found, I would like the search start again at the beginning of the text to find the first item again (kind of cycle).. you know what I mean ?
– Anatole
Jun 29 at 10:23





@Anatole you mean find duplicate item?
– Ankit Agarwal
Jun 29 at 10:24





Not really, my issue is really about the wrap around option : don't stop when the last item of page is found but continue to search to find the first item then second etc...

In fact your problem is that you were calling .find() method on container instead of window element, that's why it isn't working because it's part of windowobject and is not accessible on HTML objects.


.find()


container


window


window



Just change your code to:


if (window.find) {
var container = document.getElementById('container');
strFound = window.find(str);
if (!strFound) {
strFound = window.find(str, 0, 1);
while (window.find(str, 0, 1)) continue;
}
}



Demo:



This is a working demo along with your updated CodePen.




$('#search-btn').on('click', () => {
findString('lorem')
});

function findString(str) {
let strFound;
if (window.find) {
var container = document.getElementById('container');
strFound = window.find(str);
if (!strFound) {
strFound = window.find(str, 0, 1);
while (window.find(str, 0, 1)) continue;
}
}
if (!strFound) alert("String '" + str + "' not found!")
return;
}


#container {
width:800px;
height:200px;
overflow:scroll
}

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
