我在这样的javascript中生成了一些html代码
cell.innerHTML = '<a href="#" class="sortheader" id="sortheader_'+i+'" '+
'onclick="ts_resortTable(this, '+i+');return false;">' +
txt+'<span class="sortarrow"></span></a>';
我想调用函数ts_resortTable()但是无论onclick事件如何,我如何生成函数的“this”参数?
我尝试这样做
ts_resortTable.call(document.getElementById('sortheader_'+i), i);
和这个
ts_resortTable(document.getElementById('sortheader_'+i), i);
但它不起作用
我试图调用的函数是:
function ts_resortTable(lnk,clid) {
//save clid in cookies
$.cookie("clid", clid);
//fade to table
$('#table8k6k_progress').before('<div id="loading" style="background: #fff; position: absolute; margin-top: -25px; padding: 3px 5px; font-weight: bold;">Loading...</div>');
$('#table8k6k_progress').fadeTo('fast',0.5, function() {
TIMERSTART = (new Date()).getTime();
// get the span
var span;
for (var ci=0;ci<lnk.childNodes.length;ci++) {
if (lnk.childNodes[ci].tagName && lnk.childNodes[ci].tagName.toLowerCase() == 'span') span = lnk.childNodes[ci];
}
var spantext = ts_getInnerText(span);
var td = lnk.parentNode;
var column = clid || td.cellIndex;
var table = getParent(td,'TABLE');
// Work out a type for the column
if (table.rows.length <= 1) return;
var itm = ts_getInnerText(table.rows[1].cells[column]);
//itm = itm.substr(0,7);
sortfn = ts_sort_caseinsensitive;
if (itm.match(/^\d{1,2}[\/-]\d{1,2}[\/-]\d{2,4}\s\d\d\W\d\d$/)) sortfn = ts_sort_date;
if (itm.match(/^\d\d[\/-]\d\d[\/-]\d\d\d\d$/)) sortfn = ts_sort_date;
if (itm.match(/^\d\d[\/-]\d\d[\/-]\d\d$/)) sortfn = ts_sort_date;
if (itm.match(/^[£$]/)) sortfn = ts_sort_currency;
if (itm.match(/^[\d\.]+$/)) sortfn = ts_sort_numeric;
SORT_COLUMN_INDEX = column;
var firstRow = new Array();
var newRows = new Array();
for (i=0;i<table.rows[0].length;i++) { firstRow[i] = table.rows[0][i]; }
for (j=1;j<table.rows.length;j++) { newRows[j-1] = table.rows[j]; }
newRows.sort(sortfn);
if (span.getAttribute("sortdir") == 'down') {
ARROW = stIsIE ? ' <font face="webdings">6</font>' : ' ▾';
newRows.reverse();
span.setAttribute('sortdir','up');
} else {
ARROW = stIsIE ? ' <font face="webdings">5</font>' : ' ▴';
span.setAttribute('sortdir','down');
}
// We appendChild rows that already exist to the tbody, so it moves them rather than creating new ones
// don't do sortbottom rows
for (i=0;i<newRows.length;i++) { if (!newRows[i].className || (newRows[i].className && (newRows[i].className.indexOf('sortbottom') == -1))) table.tBodies[0].appendChild(newRows[i]);}
// do sortbottom rows only
for (i=0;i<newRows.length;i++) { if (newRows[i].className && (newRows[i].className.indexOf('sortbottom') != -1)) table.tBodies[0].appendChild(newRows[i]);}
// Delete any other arrows there may be showing
var allspans = document.getElementsByTagName("span");
for (var ci=0;ci<allspans.length;ci++) {
if (allspans[ci].className == 'sortarrow') {
if (getParent(allspans[ci],"table") == getParent(lnk,"table")) { // in the same table as us?
allspans[ci].innerHTML = '';
}
}
}
span.innerHTML = ARROW;
//fadeTo
$('#table8k6k_progress').fadeTo('fast', 1);
//remove div loading
$('#loading').remove();
});
//alert("Time taken: " + ( (new Date()).getTime() - TIMERSTART ) + "ms");

要调用函数并显式控制函数内部的this
,请使用函数的call方法
ts_resortTable.call(document.getElementById('sortheader_'+i), i)
this
设置为document.getElementById('sortheader _'+ i)。i

根据您输入的内容
$('sortheader_' + i)
由于这不是MooTools,您需要为选择器执行此操作。
$('#sortheader_' + i)
您需要在jQuery中使用CSS选择器。

致电
onclick="ts_resortTable(this, '+i+');
ts_resortTable函数的第一个参数是<a>

答案 3 :(得分:0)
的document.getElementById( 'sortheader _' + I)
当我在文档就绪事件上启动函数时,尚未生成带有id的链接。因此解决方案是延迟功能的启动;)
