按文本选择 jquery 中的选项

Question

This should be a fairly simple task but all the solutions online never worked for me.

I have an array that contains loan types:

var arrLoanType = {
        1:"Regular Loan",
        2:"Emergency Loan",
        3:"Special Loan",
        ...}

I compare the above to entries in the database, so that the ones existing in the database are removed from the array.

I've looped through them via the code below:

$.each(arrLoanType, function(index, value){
    $("#loanType").append("<option value='"+index+"'>"+value+"</option>");
});

Now to the question, what I want to happen is to have a default selected field based on the option's text. This is my code:

$('#loanType option').filter(function () { 
   return $(this).text() == selectedLoan; 
}).attr('selected','selected');

where selectedLoan is from a hidden input field var selectedLoan = $("#loanSelected").val();

It just doesn't work. This is how my HTML code structure looks like after the $.each is generated:

<select name="" id="loanType" class="form-control" required="">
    <option value="" selected="" disabled="" hidden="">Select Loan Type...</option>
    <option value="1">Regular Loan</option>
    <option value="2">Emergency Loan</option>
    <option value="3">Special Loan</option>
...

I already tried removing "selected" attribute on the first item but it still doesn't work. Any help would be appreciated. Thanks.

Answer 1

you can select the default value on creation itself

$.each(arrLoanType, function(index, value){
    if(value == selectedLoan)
        $("#loanType").append("<option value='"+index+"' selected>"+value+"</option>");
    else
        $("#loanType").append("<option value='"+index+"'>"+value+"</option>");
});

the if else checks the text is equal to selected loan or not and add selected attribute in creation itself I think it solves your problem

Seems fine please have a look. Any error in the console? perhaps you forget to include jquery lib or not inside doc ready?

 $(document).ready(function(e) { var arrLoanType = { 1:"Regular Loan", 2:"Emergency Loan", 3:"Special Loan"} $.each(arrLoanType, function(index, value){ $("#loanType").append("<option value='"+index+"'>"+value+"</option>"); }); $('#loanType option').filter(function () { return $(this).text() == $("#loanSelected").val(); }).attr('selected','selected'); });
