如何在jQuery .html（）函数中打印javascript数组值？

Question

I have a JavaScript array that contains a set of strings. I want to display them in a HTML div element by line by line using j Query or JavaScript.

My code is up to now:

var data = data;
for (i = 1; i <= data.length; i++) {

  data[i] = data[i] + '<br />';

  $(target).html('<a>'+data[i]+'</a>');
}

My data is displayed in this moment right now.

Labelling MachinesLabels - Plastic, Metal, Foil etcLabels FabricLaboratories - MedicalLaboratories - TestingLaboratory Equipment & SuppliesLaboratory Equipment Services & Calibration

I want them displayed like this as links (inside tags):

Labelling Machines
Labels - Plastic, Metal, Foil etc
Labels Fabric
Laboratories - MedicalLaboratories - Testing
Laboratory Equipment & Supplies
Laboratory Equipment Services & Calibration

Thanks in advance

Answer 1

You should add the breaks outside of the link tags and use .html() only once, as it completely replaces the innerHTML of the given element, ie

str = "";
for (i = 1; i <= data.length; i++) {
    str += "<a>" + data[i] + "</a><br />";
}
$(target).html(str);

I would suggest another approach, to use innerHTML (javascript) or append (jquery) as another answer has already mentioned

for (i = 1; i <= data.length; i++) {
    target.innerHTML += "<a>" + data[i] + "</a><br />";
}

Answer 2

var data = data;
var str = '';
for (var i = 1; i <= data.length; i++) {

  str += `<a>${data[i]}<br /></a>`;

}
$(target).html(str);

Try this.

The cleanest way will be wrapped in a div. And you need to use .append() method to not override the initial data that is already added to the target.

 var data = ["Hello", "World", "Lorem", "Ipsum", "More length"]; for (var i = 0; i < data.length; i++) { $("#result").append('<div><a href="#" class="link">' + data[i] + '</a></div>'); } 

 .link { color: #5ca5cc; margin-bottom: 10px; text-decoration: none; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="result"></div> 

Clean and more simple code along with working demo.

Answer 4

Your code is incomplete here.Not sure if you have declare variable i anywhere in code.Also you are starting to loop from 1st index

Instead of appending to DOM on every iteration,create a string and concat the value to it. Append it on completion of the iteration.

var data = data,
htmlString="";
for (var i = 0; i <= data.length; i++) {
htmlString+= data[i] + '<br />';
}
$(target).append(htmlString);

Answer 5

Instead of a for/loop you could use ES6 in one line with map and a template literal .

$(target).html(arr.map(el => `<a>${el}</a><br/>`));
