如何在javascript或jQuery中为每个div分配JS数组值？

Question

<script type="text/javascript">
    window.onload =init;

    function init(){

        $rlt = [1, 0, 0];

        //How to assign value of $rlt to each div
    }

</script>

        <div id="block1"></div>
        <div id="block5"></div>
        <div id="block7"></div>

How to assign value of $rlt to each div in javascript or Jquery?

Final result should be:

        <div id="block1">1</div>
        <div id="block5">0</div>
        <div id="block7">0</div>

Answer 1

Here you go:

$( 'div' ).each( function ( i ) {
    $( this ).text( $rlt[i] );
});

or with regular JavaScript:

[].forEach.call( document.getElementsByTagName( 'div' ), function ( div, i ) {
    div.textContent = $rlt[i];
});

Answer 2

Some thing like:

var rlt = [1, 0, 0];

// Only if ID starts with block
$( "[id^=block]" ).each(function( index ){
    if( !rtl[index] ) return false; // Stop when out of index.
    $( this ).html( rlt[index] );
});

Answer 3

This should do it:

$(document).ready(function() {
    var $rlt = [1, 0, 0];
    $("div[id^=block]").each(function(i) {
        $(this).html($rlt[i]);
    });
});

Answer 4

Assuming you want to add the array values sequentially to each of the divs you can try this provided you include jQuery library into your page.

$(document).ready(function() {
    var $rlt = [1, 0, 0];
    $("div[id^=block]").each(function(i) {
        $(this).html($rlt[i].toString());
    });
});

Answer 5

you can easily do it just using javascript. jQuery is not required for this small code. you can avoid need of jquery plugin.

<script type="text/javascript">
window.onload = init;
function init(){
var $rlt = [1, 0, 0];
document.getElementById("block1").innerHTML  = $rlt[0];
document.getElementById("block5").innerHTML  = $rlt[1];
document.getElementById("block7").innerHTML  = $rlt[2];
}
</script>

Answer 6

var divs = getElementsByTagName('div');

for(var i = 0; i < $rlt.length && i < divs.length; i++) {
     divs[i].innerHTML = $rlt[i];
}

Or for a jQuery alternative:

var divs = $('div');

divs.each(function(i, div){
     div.innerHTML = $rlt[i];
});
