[英]How to get table cell value with javascript by attribute
function getSelectedCopyDates() {
var arr = new Array();
//for every row that has a checked checkbox
$("tr").has(".noteCheckBox:checked").each(function (i) {
if ($(this).id !== "checkAllNotes"){//since this doesn't have a "abbr=..." it breaks the code below "# syntax error"
//push the value of column(FName, LName) into the array
arr.push($("#" + this.id + "> td[abbr='EventDate'] > div").text());
}
});
return arr;
}
如果通過“單元格值”來查找<td>
的文本,則可以執行this
:
HTML :
<table>
<tr>
<td align="center" abbr="FName, LName">RAWR</td>
</tr>
</table>
jQuery的 :
$("td[abbr='FName, LName']").text();
您可以使用jQuery的.text()
方法來獲取給定元素內的值。
編輯 :
看到您只需要獲取<td>
,其中包含選中的復選框,因此這可能對您有用:
$("td[abbr='FName, LName'] > input:checked").parent().text();
找到所有包含已選中輸入的td[abbr='FName, LName'
,然后獲取父元素that的文本。
//You won't need the on change event for you code. I only added it here to show you what happens when there are values and when there are no values.
$("input").on("change", function(){
var arr = new Array();
//for every row that has a checked checkbox
$("tr").has(".noteCheckBox:checked").each(function(i){
//push the value of column 5 (FName, LName) into the array
arr.push($("#"+this.id + "> td > div.c5").text());
});
//Print the array to the console.
console.log(arr);
});
編輯 :
您的功能應為:
function getSelectedInvestigatorNames() {
var arr = new Array();
//for every row that has a checked checkbox
$("tr").has(".noteCheckBox:checked").each(function(i){
//push the value of column 5 (FName, LName) into the array
arr.push($("#"+this.id + "> td[abbr='FName, LName'] > div").text());
});
return arr;
}
