在javascript中维护结构中的PHP解码编码字符串

In PHP I have data scraped a sit and produced the following string ( shortened there are over 130 rows).

[{
  "0name":"LNE-54V150WAAA DISTRI # 1145-1187-ND",
  "1name":"Delta Electronics Inc",
  "2name":"LED DRIVER CC/CV AC/DC 54V 2.8A",
  "3name":"56 In Stock",
  "4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More",
  "5name":"Buy Now"
}, {
  "0name":"LNE-54V150WDAA DISTRI # 1145-1188-ND",
  "1name":"Delta Electronics Inc",
  "2name":"LED DRIVER CC/CV AC/DC 54V 2.8A",
  "3name":"53 In Stock",
  "4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More",
  "5name":"Buy Now"
}]

I use echo '['.$arrayBare.']';

When I paste this into http://json.parser.online.fr it show as a json array correctly.

Now I need to use this in javascript. I have tried various methods in PHP and javascript but cannot maintain the structure.

    Simple examples of json decoding in PHP and JavaScript

    Try PHP's json_decode function. This is tested in PHP and it works:

    $str = '[{"0name":"LNE-54V150WAAA DISTRI # 1145-1187-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 2.8A","3name":"56 In Stock","4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More","5name":"Buy Now"},{"0name":"LNE-54V150WDAA DISTRI # 1145-1188-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 2.8A","3name":"53 In Stock","4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More","5name":"Buy Now"},{"0name":"LNE-54V185WDAA DISTRI # 1145-1190-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 3.45A","3name":"49 In Stock","4name":"100 £37.7587 50 £41.1914 25 £43.9376 10 £44.6240 5 £46.6840 1 £48.0600 See More","5name":"Buy Now"},{"0name":"PME264NE5470MR30 DISTRI # 399-7467-ND","1name":"KEMET Corporation","2name":"CAP FILM 0.047UF 20% 660VAC RAD","3name":"26 In Stock","4name":"5000 £0.9579 2500 £0.9948 1000 £1.0316 500 £1.1790 100 £1.5474 10 £2.0260 1 £2.5000 See More","5name":"Buy Now"},{"0name":"LNE-54V185WAAA DISTRI # 1145-1189-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 3.45A","3name":"23 In Stock","4name":"100 £37.7587 50 £41.1914 25 £43.9376 10 £44.6240 5 £46.6840 1 £48.0600 See More","5name":"Buy Now"},{"0name":"SIT3808AI-22-25NE-54.000000Y DISTRI # SIT3808AI-22-25NE-54.000000Y-ND","1name":"SiTime Corporation","2name":"OSC MEMS VCXO 54.0000MHZ LVCMOS","3name":"Temporarily Out of Stock","4name":"1000 £3.9582","5name":"Buy Now"},{"0name":"SIT3808AI-22-25NE-54.000000T DISTRI # SIT3808AI-22-25NE-54.000000T-ND","1name":"SiTime Corporation","2name":"OSC MEMS VCXO 54.0000MHZ LVCMOS","3name":"Temporarily Out of Stock","4name":"3000 £3.9582","5name":"Buy Now"},{"0name":"SIT3808AC-DF-33NE-54.000000Y DISTRI # SIT3808AC-DF-33NE-54.000000Y-ND","1name":"SiTime Corporation","2name":"OSC MEMS VCXO 54.0000MHZ LVCMOS","3name":"Temporarily Out of Stock","4name":"1000 £5.7821","5name":"Buy Now"},{"0name":"SIT3808AC-DF-33NE-54.000000T DISTRI # SIT3808AC-DF-33NE-54.000000T-ND","1name":"SiTime Corporation","2name":"OSC MEMS VCXO 54.0000MHZ LVCMOS","3name":"Temporarily Out of Stock","4name":"3000 £5.7821","5name":"Buy Now"},{"0name":"LNE-54V185WAAA","1name":"Delta Electronics Inc","2name":"54V 185W IP65 VR ADJUST","3name":"456","4name":"$68.4714","5name":"Buy Now"},{"0name":"LNE-54V185WAAA","1name":"Delta Electronics Inc","2name":"54V 185W IP65 VR ADJUST","3name":"20","4name":"$61.5800","5name":"Buy Now"},{"0name":"LNE-54V150WAAA","1name":"Delta Electronics Inc","2name":"54V 150W IP65 VR ADJUST","3name":"506","4name":"$64.9857","5name":"Buy Now"},{"0name":"LNE-54V150WAAA","1name":"Delta Electronics Inc","2name":"54V 150W IP65 VR ADJUST","3name":"19","4name":"$58.4700","5name":"Buy Now"},{"0name":"LNE-54V150WDAA","1name":"Delta Electronics Inc","2name":"54V 150W IP67 DIMMING","3name":"506","4name":"$64.9857","5name":"Buy Now"},{"0name":"LNE-54V150WDAA","1name":"Delta Electronics Inc","2name":"54V 150W IP67 DIMMING","3name":"20","4name":"$58.4700","5name":"Buy Now"},{"0name":"LNE-54V185WDAA","1name":"Delta Electronics Inc","2name":"54V 185W IP67 DIMMING","3name":"20","4name":"$61.5900","5name":"Buy Now"},{"0name":"LNE-54V185WDAA","1name":"Delta Electronics Inc","2name":"54V 185W IP67 DIMMING","3name":"510","4name":"$68.4714","5name":"Buy Now"},{"0name":"LNE-54V185WACA DISTRI # LNE-54V185WACA","1name":"Eltek","2name":"LED DRVR Module 1-CH IP65 58V 3.45A (Alt: LNE-54V185WACA) RoHS: Compliant","3name":"Europe -

    In Javascript use Javascript's JSON.parse():

    var str = '[{"0name":"LNE-54V150WAAA DISTRI # 1145-1187-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 2.8A","3name":"56 In Stock","4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More","5name":"Buy Now"},{"0name":"LNE-54V150WDAA DISTRI # 1145-1188-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 2.8A","3name":"53 In Stock","4name":"100 £35.8441 50 £39.1026 25 £41.7096 10 £42.3620 5 £44.3160 1 £45.6200 See More","5name":"Buy Now"},{"0name":"LNE-54V185WDAA DISTRI # 1145-1190-ND","1name":"Delta Electronics Inc","2name":"LED DRIVER CC/CV AC/DC 54V 3.45A","3name":"49 In Stock","4name":"100 £37.7587 50 £41.1914 25 £43.9376 10 £44.6240 5 £46.6840 1 £48.0600 See More","5name":"Buy Now"},{"0name":"PME264NE5470MR30 DISTRI # 399-7467-ND","1name":"KEMET Corporation","2name":"CAP FILM 0.047UF 20% 660VAC RAD","3name":"26 In Stock","4name":"5000 £0.9579 2500 £0.9948 1000 £1.0316 500 £1.1790 100 £1.5474 10 £2.0260 1 £2.5000 See More","5name":"Buy Now"}]';

var obj = JSON.parse( str );

for ( var i = 0, l = obj.length; i < l; i++ ) {
    alert( obj[ i ]['0name'] );
}

    If you're using jQuery, looping through the array of objects can be done with $.each:

    $.each( obj, function(i,x){
  alert( x['0name'] )
});

    Update

    This is why you were getting the error regarding "invalid argument" ...

    It turns out that toolfolks.com is outputing what you think is json, but since they are not serving it properly, it's coming in with HTML entities, and a bunch of extra whitespace. You don't see that when you look at in in your browser, but trust me it's there. So, to accomodate for their lunacy:

    <?php

$json_response = file_get_contents('http://toolfolks.com/techy/parsefindchips2.php');

// Remove HTML entities
$json_response = html_entity_decode( $json_response );

// Remove the white space
$replaced = preg_replace('/\s\s+/', ' ', $json_response);

$arr = json_decode( $replaced, TRUE );

foreach( $arr as $el )
{
    echo '<p>' . $el['0name'] . '<br />' . 
        $el['1name'] . '<br />' . 
        $el['2name'] . '<br />' . 
        $el['3name'] . '<br />' . 
        $el['4name'] . '<br />' . 
        $el['5name'] . '</p>';
}

    I definitely deserve extra points here :)
