jquery / javascript中的php echo（）函数？

Question

是否有一个jquery / javascript函数与PHP echo（）相同？

Answer 1

I suppose the closest is document.write() as it's native javascript.

However there are many methods of writing/amending text in the DOM, such as innerHtml() , innerText() and outerHtml() , as well as jQuery's html() and text() .

Answer 2

You could use

document.write(stringToWrite);

or

document.writeln(stringToWrite).

Answer 3

// This is what you are looking for
document.write('Hello world');
document.getElementById('mydiv').write('Hello world');

// jQuery
$(body).append('Hello world');
$('#mydiv').append('Hello world');

Answer 4

我想你正在寻找：

document.write( ... );

Answer 5

document.write("text"); \\javascript syntax.

使用jquery时，您可以在任何元素obj下查看文本。

 $("#mydiv").append($("#myElement").val());

Answer 6

I know there is such a simple way to go around it, and we can simply use document.write method. But the downside of that default method is that it simply appends the string passed to the method directly to the body.

In case we want specific tags to be appended we can use the function i made below. The function name is printThis() and takes three parameters text, className, idName. The text is the text which we want to append to the document, the className and idName are the name of the class and id we want to set.

 function printThis (text,className,idName){ var p = document.createElement('p') var t = document.createTextNode(text); setAttribute = function (el, attrs) { for(var key in attrs) { el.setAttribute(key, attrs[key]); } } setAttribute(p,{class:className,id:idName}) p.appendChild(t) document.body.appendChild(p) } printThis('This is a new Paragraph','newClass','newId')

If you want to edit the content of an element use html() . You can manipulate the DOM in diffrent ways. Check the docs .
