原标题:Javascript array declaration (possibly mis-using length attribute?)

I m 试图获得红字塔的内联网......

var fontTags = document.getElementsByTagName( font );
var reds = [];
var j = 0;
var i = 0; // ETA this line
for (i;i<=fontTags.length;i++) { // ETA the  i<= 
  if (fontTags[i].getAttribute( color ) ==  RED ) {
    reds[j] = fontTags[i].innerHTML;
    j++;
  }
}

javascript console告诉我,“fontTags[i]”没有定义。 我没有尝试发表任何声明,用新的阿雷拉(Array)(......)说同样的话。 帮助?

        j++;
    }

for (i=0;i<fontTags.length;i++){

check the for loop condition

for(i=0;i<fontTags.length;i++)

相反(i=0;fontTags.length;i++)
