Why doesn't array splice work with a string that has been formatted into an array using the split() method?
function _formatText(text) {
var textList = text.replace(/\s+/g, ",").split(",");
return textList.splice(1, 0, "<br />").join(" ");
}
alert(_formatText("A REALLY LONG STRING"))Utilizing the Array#splice() method will give you the array of elements that were removed. In this scenario, the returned array is empty, and you are attempting to join it.
To resolve this issue, you should reorganize your code as shown below.
function _formatText(text) {
var textList = text.replace(/\s+/g, ",").split(",");
textList.splice(1, 0, "<br />");
return textList.join(" ");
}
alert(_formatText("A VERY LONG TEXT EXAMPLE"))Forget about using the string replace method. You can simplify your code to achieve the same result.
function _modifyContent(content) {
var contentArray = content.split(/\s+/);
return contentArray.slice(0,1).concat("</br>",contentArray.slice(1)).join(" ");
}
alert(_modifyContent("A REALLY LONG SENTENCE"))$(".dropdown-toggle").click(function(event) { var target = $(event.target); if (target.is(this)) { $(this).find(".caret").toggleClass("customcaret"); } }); <div class="dropdown-toggle"> <div class="caret"></div> </div> ...
